Sessions - New York, London & AsiaOVERVIEW
This indicator draws price range boxes for the main trading sessions (Asia, London/Europe, and New York) and an optional full-day box with daily high/low labels and open/close lines. It is a chart-context tool: it shows where price traded during each session window, not buy/sell signals.
PURPOSE / WHY THIS EXISTS
Many traders need a clear visual of:
1) which session produced the day’s high or low,
2) how large the session range was,
3) how sessions overlap (for example London–New York),
4) and where the daily open sits relative to those ranges.
This script combines three session range boxes with a daily structure layer (00:00–24:00 in a fixed timezone). The components are meant to work together so you can read session behavior against the same day’s overall range without stacking several separate scripts.
WHAT IT DOES
• Asia session box — tracks high/low while the Asia window is open; freezes the box when the session ends.
• London (Europe) session box — same logic for the London window.
• New York session box — same logic for the RTH-style New York window.
• Daily box — full calendar day high/low in the same timezone.
• Daily high/low labels — marks the bar time of the daily high and low.
• Optional daily open and close/last lines with labels.
Sessions are only drawn on intraday charts. On daily and higher timeframes, session boxes are disabled (the daily layer can still apply depending on your settings).
DEFAULT SESSION TIMES
All times use the America/New_York timezone (PulseWire handles daylight saving for that zone). Defaults can be edited in the inputs:
• Asia: 20:00–05:00
• London (Europe): 03:00–12:00
• New York: 09:30–16:00
Overlaps are intentional. For example, Asia and London can share a morning window, and London and New York share a large mid-day window. The boxes stack so you can see concurrency visually.
HOW IT WORKS (CONCEPT)
1) Session membership
For each session, the script checks whether the current bar’s time falls inside the configured session string, evaluated in America/New_York.
2) Session start / end
• Session start: first bar that is inside the session after being outside.
• Session end: first bar that is outside the session after being inside.
3) Range tracking
While inside a session, the script updates running high and low from bar high/low. The live box left edge is the session start bar; the right edge follows the current bar. When the session ends, the box is fixed for that day/session instance and kept in an optional history list.
4) Daily layer
The daily open is taken from the 1D open of the symbol. Daily high/low are tracked from bar values until the New York calendar day changes, then the previous day is finalized as a historical daily box (if enabled).
5) Object limits
History depth is capped by internal safety limits so the chart does not exceed PulseWire drawing object limits on low timeframes.
HOW TO USE IT
Typical workflow on a 1m–15m chart:
1) Load the symbol you trade (indices, FX, metals, etc.).
2) Keep default session times if your process is U.S.-anchored; otherwise edit the three session inputs.
3) Use GLOBAL visibility toggles if you only need one or two sessions on screen.
4) Compare the current New York (or London) box size to recent historical boxes of the same color — this is visual context for range expansion/contraction, not a trade rule by itself.
5) Use daily high/low labels to see whether extremes printed in Asia, London, or New York.
6) Use open/close lines if you track acceptance above/below the daily open as part of your own rules.
Suggested reading order on any day:
Daily structure first (open, D Hi, D Lo) → then session boxes → then your own entry method (structure, levels, etc.). This script does not define entries, stop-loss, or take-profit.
INPUTS (MAIN GROUPS)
• Session time strings and colors for Asia / London / New York.
• Per-session show historical vs current boxes; outline-only options.
• GLOBAL toggles for each session.
• Daily box: historical and current day display.
• Daily high/low labels and colors.
• Daily open/close lines and their labels.
COLORS (DEFAULT IDEA)
• Asia — yellow tones
• London — blue tones
• New York — red tones
• Daily — lime tones
Colors are customizable so you can match your chart theme.
WHAT THIS SCRIPT IS NOT
• Not a strategy and not a signal generator.
• Not a guarantee of profitable trades or future price direction.
• Not a replacement for risk management or a complete trading plan.
• Session times are conventions (liquidity-focused windows), not a claim that one session is inherently “better” to trade.
TIPS FOR A CLEAN CHART
• Publish/use with this script alone on the chart for clarity.
• Prefer outline-only if fills feel heavy.
• Reduce historical session display if the chart becomes crowded.
LIMITATIONS
• Session logic depends on the bar timeframe: on higher intraday TFs, box edges align to those bars, not tick-perfect open/close of the clock window.
• Some symbols have thin overnight liquidity; box size then reflects that microstructure, not “quality” of a setup.
• Past session ranges do not predict the next session’s range.

Nexus Sessions Session High/Low (Asia / London / New York)Draws the running high and low of the Asia, London and New York sessions as clean horizontal
lines with labels that follow price. No boxes, no vertical dividers, no clutter — just the levels.
CORE + CARRY WINDOWS
Each session has a core window and a carry window, and the level keeps forming through both
before it locks. London's range isn't finished at 05:00 — flow from that session keeps working
the book for hours, and a high printed at 08:54 still belongs to London even though the core
ended long before. Defaults: Asia 18:00-00:00 (carry to 02:00), London 02:00-05:00 (carry to
09:30), New York 09:30-11:00 (carry to 16:00), all New York time.
SWEPT LEVELS
Once a session's core and carry are both done, its high and low lock. If price later trades back
through one, that line turns dotted and relabels itself SWEPT — while keeping its session colour,
so you can still tell at a glance whose liquidity just got taken. An untouched session extreme is
resting liquidity; a swept one is spent. Nothing gets marked swept while the level is still
forming, so a new high inside its own session never false-flags as a sweep of itself.
TWO WAYS TO DRAW THE LINE
By default each line starts on the bar that actually printed the high or low, so you can see
exactly when the level was set. Switch to Session open and the line spans the entire session
instead, showing how long the level has been in play and how much of the session traded above or
below it. Same levels, two different questions.
TIMEZONES
Defaults are New York time and the standard core windows, so it lines up with what you're already
reading. Each session can also be switched to its own market's local time — which changes nothing
for about 48 weeks a year, and differs only in the ~4 weeks when the US and UK clocks disagree.
Japan observes no DST at all, so an Asia window pinned to New York drifts against Tokyo at every
US changeover. Pick native if you want the literal London open; leave it on New York to match
every other session tool.
Full colour control per session — separate high, low and swept colours — plus infinite or
fixed-length extension, adjustable label offset, and per-session toggles.

Previous Day Key Levels# Previous Day Key Levels
Previous Day Key Levels automatically plots the key reference points I use to frame each trading day:
* Previous RTH High and Low
* Asia High and Low
* London High and Low
The indicator is designed to work on an RTH chart while still calculating the Asia and London ranges from extended-hours data. Each level is drawn as a clean horizontal reference with a named label and a matching price marker on the right axis.
## How to use it
These levels help organize the market into clear areas of potential reaction, acceptance, rejection, breakout, or failed breakout.
Previous Day High and Low are especially useful as major reference points for the current RTH session. Price holding above or below them can support a directional thesis, while tests and rejections can highlight potential reversals or rotational conditions.
Asia and London Highs/Lows provide additional intraday structure before and during New York trading. They can act as liquidity targets, breakout points, or areas where an early New York move may stall, reverse, or accelerate.
The Asia range updates when the Asia session ends, and the London range updates when London ends. Previous Day High/Low refresh for the next RTH session.
## Pairing with Volume Profile
This indicator is intended as a supporting structure tool—not a standalone entry signal.
For a fuller market read, pair it with a Volume Profile indicator that provides:
* POC: the session’s highest-volume price area
* VAH: Value Area High
* VAL: Value Area Low
When a key session level overlaps with POC, VAH, or VAL, that confluence can make the area more meaningful. For example:
* A Previous Day High near VAH may act as a more significant resistance or breakout-acceptance area.
* A Previous Day Low near VAL may become a higher-quality support or breakdown-rejection zone.
* An Asia or London extreme aligning with POC can highlight a potential magnet, decision point, or support/resistance area.
Use the levels alongside price action, market context, and volume behavior. They are reference points—not guarantees—and are most useful for forming a structured trade idea and defining risk around meaningful market locations.
Indicator
RPFXBYDAN - Untouched Session Liquidity - Asia / London / NYRPFXBYDAN - Untouched Session Liquidity — Asia / London / NY
**What this script does**
This indicator marks the high and low of each Asia, London, and New York trading session and projects those two levels forward as horizontal lines. Unlike a standard session-range indicator that leaves every past level on the chart, this one automatically deletes any level the moment price reaches it. The result is a running inventory of the recent session highs and lows that price has NOT yet run — the liquidity that is still "live" on the chart.
By default the script keeps the ten most recent sessions per region so you can see whether the current market is respecting, sweeping, or ignoring older session extremes.
**Why session highs and lows matter**
Session highs and lows tend to attract price because they collect a predictable pool of stop-loss orders — protective stops from participants who entered inside the previous session's range. Price often gravitates toward these levels, sweeps the liquidity, and reverses. Knowing which specific levels are still untaken (versus already mitigated) is more actionable than seeing every historical level indiscriminately, because only untaken levels still hold that liquidity.
**How the script works, step by step**
1. On every bar, the script checks whether the bar falls inside the Asia, London, or New York session window, using Pine's timezone-aware time function so detection is correct on any chart regardless of the user's timezone settings.
2. While a session is active, it tracks the running high and low and remembers the bar index at which each was set.
3. The instant a session closes (the first bar the session check flips from true to false), it draws two horizontal lines anchored at those bar indexes — one at the session high, one at the session low — with a text label naming the region.
4. Each new line and label is pushed onto a per-region array. If the array now holds more than the configured lookback count (default ten), the oldest entry is shifted off and deleted.
5. On every subsequent bar, the script walks the array of active lines and compares the current candle's high to each high level and the current candle's low to each low level. Any line whose level has been reached is deleted along with its label. Any line not yet touched has its right edge advanced so the projection stays anchored to the current bar.
The touch check is the mechanism that keeps the chart focused only on liquidity that hasn't been taken yet — it's what differentiates this from a normal "show previous session range" indicator.
**Timezone handling**
The default Auto mode detects each session in its own home timezone: Asia in Tokyo time, London in London time, and New York in New York time. Because Pine's time function accepts a timezone argument, the detection is correct regardless of what timezone your chart is set to, and daylight saving transitions are handled automatically. If you'd rather have all three sessions interpreted in one specific timezone (for example, always in your local one), the location dropdown lets you select from a menu of common cities and UTC offsets, and the session windows will be read in that timezone instead.
**Inputs**
- Your Location / Timezone — Auto (recommended) or a specific city / UTC offset
- Asia, London, New York Session windows — defaults calibrated to each session's home clock time
- Sessions to Keep — how many recent sessions per region to display (default 10)
- Colors per region, line width, line style, right-extension length, label toggle
**How to use it**
Add the indicator to a 5-minute, 15-minute, 30-minute, or 1-hour chart of any symbol. Give the chart a few days of history to load so the script can walk through session closes and populate the levels. Watch how price interacts with the untaken lines — a clean sweep of an old session high can precede a reversal, while price trading through a level without pausing suggests continuation. Because touched levels are removed automatically, whatever remains on the chart at any moment is the current "menu" of session liquidity worth watching.
Works on any instrument, though it's most useful on FX pairs, index futures, and crypto where session structure is meaningful. Higher timeframes (4H+) compress sessions into a single bar and reduce the value of the lines.
**Notes**
Session detection uses each session's home timezone in Auto mode; in manual mode you select a single timezone that applies to all three. Both modes automatically handle daylight saving. Indicator
EdgeMatrix SessionsUnlike most session indicators that only mark static open or close levels, EdgeMatrix Sessions draws a live expanding range box for each session that updates bar by bar and remains as a permanent reference level after the session closes
EdgeMatrix Sessions draws real-time high and low range boxes for the four major global trading sessions directly on the chart. The sessions covered are Tokyo, London, New York, and Sydney.
Each session box begins drawing at the open of the session window and expands automatically bar by bar as price establishes new highs or lows within that session period. When the session closes, the box remains on the chart as a permanent reference level, giving traders a visual record of where price was accepted during each major market period.
Session boundary detection is handled using a UTC offset input, which allows the indicator to align session times accurately regardless of the trader's local timezone or broker server time. Each session has its own independent color input and can be toggled on or off individually. Session time ranges are fully adjustable for traders whose broker uses non-standard open and close times.
The indicator works on all asset classes including Futures, Forex, Crypto, and Indices on any timeframe.
How to use: Set the UTC offset to match your broker server time. Enable or disable each session with the toggle inputs. The boxes draw and expand automatically during active session hours and remain as static reference levels after each session closes. Indicator
Session Bias Relay Map [AGPro Series]Session Bias Relay Map
🧠 Core Idea
Did Asia, London, and New York pass the same bias forward, or did the next session reject the market narrative?
📌 Overview / What it does
Session Bias Relay Map is an intraday session-structure tool built to visualize how directional bias moves from one major trading session to the next.
The script tracks Asia, London, and New York session ranges, scores each session's directional bias, and classifies whether the active session confirms, conflicts with, or reverses the previous session's narrative.
It does not predict price direction, automate trades, or claim that a session handoff must continue. It is a structured visualization and decision-support map for session bias, market narrative, and intraday context.
🎯 Purpose & Design Philosophy
Many session tools draw boxes, highs, lows, or kill zones.
This script was built to answer a more contextual question:
Did the next major session accept the prior session's directional story, or did it break the handoff?
The design goal is to help traders read sessions as a relay of market intent instead of isolated time windows. It supports discretionary market reading, session review, and intraday structure analysis.
⚡ Why This Script Is Different
Most session indicators focus on time blocks, session highs, and session lows.
This script does NOT stop at drawing session boxes.
Instead, it evaluates how each session behaves relative to the prior session. It scores bias strength, detects handoff confirmation, identifies conflict, and highlights reversal pressure when the active session builds a strong opposite narrative.
⚙️ Methodology
1. Session Detection
The script tracks configurable Asia, London, and New York session windows using the chart symbol's exchange timezone.
2. Session Range Mapping
For each session, it records open, high, low, close, midpoint, bar count, and live range behavior.
3. Bias Scoring
Session bias is scored using body pressure, close location inside the session range, and optional relative volume confirmation.
4. Relay Evaluation
London is compared against the completed Asia bias.
New York is compared against the completed London bias.
5. Visual Output
The chart displays session boxes, midpoint rails, centered session labels, relay event labels, right-side tags, alerts, and a compact AG Pro decision panel.
🗺️ How to Read the Chart
Session Boxes = the active session range built from each configured time window.
Centered Labels = the session name, current bias, relay state, and quality score.
Midpoint Rails = the middle of each session range, useful for reading control and balance.
Relay Event Labels = confirmation, conflict, or reversal events when a later session responds to the prior session.
Right-Side Tags = the current relay state and active session bias.
Panel = summarizes active session, relay state, bias score, prior session, session quality scores, next context, and timeframe scope.
🚦 Signals & States
• RELAY CONFIRMED → the active session supports the previous session's directional bias.
• RELAY REVERSAL → the active session builds strong bias opposite to the previous session.
• BIAS CONFLICT → the active session does not clearly confirm the previous session.
• FIRST LEG → Asia is building the first session bias for the daily relay.
• WAIT HANDOFF → the active handoff does not yet have enough evidence.
• BULLISH → the session is closing with bullish range pressure.
• BEARISH → the session is closing with bearish range pressure.
• NEUTRAL → the session does not have enough directional pressure.
🔔 Alerts Logic
Alerts trigger when a major relay state appears.
• Session Bias Relay Confirmed → the active session confirmed the directional bias passed from the previous session.
• Session Bias Conflict → the active session failed to confirm the previous session and is showing conflict.
• Session Bias Reversal → the active session built strong bias opposite to the previous session.
Alerts are attention markers, not trade instructions.
🧩 Confluence Logic
The context becomes stronger when:
• The previous session has a clear directional bias
• The active session has enough bars to evaluate
• The active session bias score is above the confirmation threshold
• Price closes with clear range position
• Relative volume supports participation
• The relay label and panel state agree
If these elements do not align, the script avoids forcing a strong directional interpretation.
📊 When to Use
• Intraday session analysis
• Forex, crypto, index futures, and liquid stock index products
• Asia-to-London handoff review
• London-to-New-York handoff review
• Market narrative tracking
• Session range and bias studies
• 15m, 30m, 1H, and 2H charts
⚠️ When NOT to Use
• Daily, weekly, or monthly charts
• Very low-liquidity symbols
• Markets with irregular or meaningless session windows
• Extremely noisy conditions where session closes do not carry useful information
• Situations where a single session should not be over-interpreted
• Symbols where the chart exchange timezone does not match the intended session model
🎛️ Key Inputs
• Asia Session → defines the first session window used to build the initial bias.
• London Session → defines the second session window used to evaluate the Asia handoff.
• New York Session → defines the third session window used to evaluate the London handoff.
• Max Chart TF Minutes → limits the largest timeframe that should build the relay map.
• Bias Confirmation Threshold → controls how strong a session must be before it can confirm a relay.
• Conflict Threshold → controls when a session is treated as weak or conflicted.
• Minimum Handoff Bars → prevents early-session noise from printing premature relay labels.
• Use Volume Confirmation → adds relative volume pressure to the bias score.
• Show Session Boxes → controls the main visual range boxes.
• Show Relay Event Labels → controls confirmation, conflict, and reversal labels.
• Label Font Size → controls chart label and tag text size.
• Panel Font Size → controls panel text size.
🖥️ Interface & Visual Design
The visual hierarchy is built around the session relay story.
Session boxes define the time windows.
Centered labels make each session readable without hunting through the chart.
Relay labels highlight the important handoff moments.
Right-side tags keep the current state visible.
The AG Pro panel summarizes the active session context in a clean, compact format.
🧪 Practical Usage Workflow
1. Choose session windows that match the market being studied.
2. Let Asia build the first bias leg.
3. Watch whether London confirms, conflicts with, or reverses Asia.
4. Watch whether New York confirms, conflicts with, or reverses London.
5. Use the panel to check relay state, active bias, quality score, and timeframe scope.
6. Interpret the result inside broader market structure, liquidity, and volatility context.
🔍 Interpretation Guidelines
A relay confirmation does not guarantee continuation. It means the active session is supporting the prior session's directional bias according to the script's rule set.
A relay reversal does not guarantee a full trend reversal. It means the active session is building strong opposite pressure relative to the previous session.
A bias conflict is not a failure. It is useful information that the market narrative is not clean.
The best use is contextual: combine the relay state with support, resistance, liquidity, volume, and higher-timeframe structure.
🚫 What This Script Is NOT
This script is not a prediction engine.
It is not financial advice.
It is not an auto-trading system.
It does not provide guaranteed entry or exit signals.
It is not a generic session box indicator.
It is not a kill-zone strategy.
⚠️ Limitations & Transparency
Session settings matter. Poorly selected session windows can produce weak or misleading context.
Timeframe differences can affect how session handoffs appear.
Low-liquidity markets can distort bias scores.
Markets with irregular trading hours may need custom session inputs.
Relative volume can help, but it does not guarantee better interpretation in every market.
🧠 Market Context Notes
Session behavior is often shaped by liquidity, regional participation, volatility expansion, and macro timing.
The same relay state can mean different things depending on whether the market is trending, ranging, or reacting to news.
The script is strongest when used as a narrative map, not as a standalone decision machine.
🧾 Use Case Examples
• If Asia builds a bullish range and London also closes with strong bullish pressure, the relay may show confirmation.
• If Asia builds bullish pressure but London quickly forms strong bearish pressure, the relay may show reversal.
• If London begins with weak movement and no clear range pressure, the relay may show conflict or wait for more evidence.
🧱 System Philosophy
Session Bias Relay Map is part of the AGPro Series approach to decision-support tools:
clear structure, premium chart readability, honest interpretation, and no promise of certainty.
The goal is to help traders see market context faster without turning analysis into signal spam.
🔐 Non-Promise Statement
No script can know the future.
No session handoff is guaranteed.
No signal should be interpreted without broader market context.
📉 Risk Disclosure
Trading involves risk.
Markets can move unpredictably.
This script is for educational and analytical purposes only.
It does not provide financial advice or guaranteed trading outcomes.
Users remain responsible for their own decisions.
📚 Educational Note
Use this script to study how market participation changes across sessions.
The value is not only in the label. The value is in learning how the session narrative develops, confirms, conflicts, or reverses over time.

Session Killzones ICT ConceptSession Killzones - ICT Concept
Session Killzones plots the four standard ICT killzone sessions
(Asia, London, NY AM, NY PM) in New York time. It tracks unswept
session highs and lows in real time, fires alerts on sweeps, and
displays a compact session info panel with countdown.
Built for ICT traders who need to know which session levels are
still active and which have already been taken.
SESSIONS
Draws session boxes and boundary lines for each killzone in New
York time with automatic DST handling (EDT/EST). Each session is
fully customizable: name, time range, and color.
Default sessions (New York time):
Asia: 20:00 - 00:00
London: 02:00 - 05:00
NY AM: 08:30 - 11:00
NY PM: 13:30 - 16:00
Each session can be toggled on/off independently. Time ranges can
be modified to match your broker's session definition.
UNSWEPT LEVELS
When a session closes, its high and low are extended forward as
dashed lines. These are unswept levels session liquidity that
price has not yet taken.
When price reaches an unswept level, the line is automatically
removed from the chart. No manual cleanup needed. This gives a
live, self-cleaning view of which session levels still matter.
Sweep events fire an alert. Alerts are available for high sweeps
and low sweeps independently.
SESSION PANEL
A compact info panel shows session context at a glance. Three
detail levels:
Simple - shows the active session name and time remaining (or next session and time until open). Standard - adds today's percentage range for each session that has occurred, with direction indicator relative to session open.
Advanced - includes unswept level prices from all closed sessions directly in the panel, alongside the session breakdown.
SESSION COUNTDOWN
Inside a session: "NY AM - 1h 23m left"
Between sessions: "London in 4h 10m"
Color indicators :
Green: session is active
Yellow: less than 15 minutes remaining (closing warning)
Gray: currently between sessions
The countdown adapts to custom session times. If you change the
London session to 01:00-04:00, the countdown reflects that.
HOW TO USE
Session boxes show the developing high and low of each killzone as the session progresses.
Dashed lines extending beyond the box are unswept levels. These represent liquidity that price has not yet reached.
When a dashed line disappears, that level has been swept. It is no longer an active reference.
Use the percentage range in Standard mode to gauge which sessions were high-range versus low-range days.
Use the countdown to plan your analysis around session opens and closes. Most high-probability ICT setups occur within the first 30 to 90 minutes of a killzone.
Enable alerts on sweep events to get notified the moment a session high or low is taken, even if you are not at the screen.

NOTES
Session Killzones is open source under CC BY-NC-SA 4.0 and is intended for educational purposes only. Nothing in this script constitutes financial advice or a recommendation to buy or sell any instrument.
The DST resolver calculates timezone offset from bar time rather than the system clock, which means the indicator behaves correctly in PulseWire replay mode. If you replay to November 2023, the resolver returns EST, not the current wall-clock timezone.
The indicator is designed for intraday timeframes from 1M to 60M and works on any instrument available on PulseWire, though it is primarily optimized for forex majors and gold (XAUUSD).
Internally, all session state is tracked using explicit boolean arrays. No state is inferred from drawing object positions or line coordinates, which avoids a common source of bugs in session-based indicators. Indicator

ALN Sessions [NQ Stats x CantoLab]A statistical tool for NQ intraday traders built around research from NQ Stats (NQStats on twitter / nqstats.com ). Credit to NQ Stats for the original concept and data — published here as an open source indicator with permission.
Introduction
This indicator visualizes Asia and London session ranges on NQ (NASDAQ futures), then overlays statistically-derived probability levels showing how likely price is to sweep each session's high or low — based on historical pattern data compiled by NQ Stats.
How to Read the Probability Numbers
When London session closes, two horizontal lines appear — one above (London High) and one below (London Low) — each labeled with a percentage like 81.1% or 74.9%.
These numbers answer: "Historically, how often does price return to sweep this level after London closes?"
For example, if you see 81.1% on the high line, it means: in roughly 8 out of 10 historical sessions matching this pattern, price eventually traded back up to or through the London High
What happens when a level is hit?
The label updates to show in blue — confirming that level was reached
The other line's probability updates to a new conditional probability, e.g. 46% , shown in brackets
This delta tells you how the odds of sweeping the second level changed now that the first was reached
The Four Patterns (Asia vs London relationship)
The probabilities change depending on how London's range relates to Asia's range that day. The indicator detects four patterns automatically:
London Engulfs Asia — London trades both above AND below Asia's range. The most expansive session structure.
Asia Engulfs London — Asia's range fully contains London's range. London consolidates inside the prior overnight range.
London High Break — London breaks only above Asia's high, leaving Asia's low intact.
London Low Break — London breaks only below Asia's low, leaving Asia's high intact.
Each pattern has its own set of historical probabilities, so the percentages you see are always contextual to that day's Asia/London relationship — not a fixed number.

⚠️ Important
This is a statistical study indicator. It does not guarantee that the London high or low will be hit. Over a large sample, this is the expected behaviour based on 10 years of NQ data. It is best combined with other confluences to confirm direction — this indicator alone is not a strategy.

Session Reaction Map [AGPro Series]Session Reaction Map
🔷 OVERVIEW
Session Reaction Map is a premium intraday study that maps how price reacts to the most important daily and weekly reference levels right at the opens of the Asia, London and New York sessions. Each session open is evaluated inside a fixed measurement window, and the resulting reaction is broken down into four dimensions: dominant move, close follow-through, wick rejection and counter-move penalty. The output is a single 0-100 reaction score that is then translated into tier-coded labels, premium reaction zones, an active reference band and a compact status panel, so you can instantly read what happened at each session open without scrolling through candles.
The indicator is designed for discretionary traders, systematic traders, SMC and price action practitioners who want a clean, consistent and quantitative way to read session open behaviour around PDH, PDL, PDM, Daily Open and Weekly Open. Reactions are drawn as directional zones (bull zones above the reference and bear zones below), with up or down pointing labels centered on the reaction, so orientation is always unambiguous.
🧭 UNIQUE EDGE
Most session open tools only mark time windows or highlight levels. Session Reaction Map goes further and quantifies the quality of the reaction itself. Four independent dimensions are measured against a fixed ATR-normalized baseline, and the final score determines not only whether a label is shown but also how prominent it is. Elite scores (80+) get the strongest visuals; strong scores (70-79) get a slightly softer treatment; watch scores (55-69) are coded as caution; anything below 55 is filtered out by default.
This separation between detection (a session open near a reference) and evaluation (the reaction quality score) is the core edge. It lets you focus only on the best intraday reactions and discard noise automatically, while still being able to audit every component by adjusting the ATR length, touch tolerance, evaluation window and score thresholds.
⚙️ METHODOLOGY
Session detection uses the chosen timezone and three session windows (Asia, London, New York), each with its own editable open range. When a session open occurs, the script checks whether the open price is within an ATR based touch tolerance of any enabled reference level (Previous Day High, Previous Day Low, Previous Day Mid, Daily Open or Weekly Open). If so, a reaction window is engaged on that bar and tracked for a configurable number of bars.
During the reaction window, the live zone, reference band and dashed reference line are updated in real time. When the window completes, the final score is computed as:
• Dominant move score (up to 45 points) - scaled against 1.20 x ATR
• Close follow-through score (up to 30 points) - scaled against 0.90 x ATR
• Wick rejection score (up to 15 points) - scaled against 0.50 x ATR
• Counter-move penalty (up to -20 points) - scaled against 1.00 x ATR
The sum is clamped into the 0-100 range and mapped into four tiers: Elite, Strong, Watch and Weak. The dominant direction of the reaction (up or down) is determined by comparing the upside excursion from the reference to the downside excursion from the reference during the window.
🎯 SIGNALS AND VISUALS
• Reaction zones - rectangular areas connecting the reference level with the reaction extreme, tier-coded by score and bias
• Active reference band - a thin accent band around the current reference level during a live reaction window
• Dashed reference line - marks the exact reference price while the reaction is being measured
• Tier-coded labels - up-pointing labels below bullish reactions and down-pointing labels above bearish reactions, centered on the reaction window
• Session dots - small colored markers that optionally display only on valid events, keeping the chart clean
• Active measurement highlight - an ultra-soft background shade on bars inside a live reaction window
Labels use a ring buffer overlap check, so dense multi-session conditions do not pile labels on top of each other. When two labels would visually conflict, the higher-scored reaction wins.
🛠️ KEY INPUTS
Sessions - enable/disable and edit Asia, London and New York session windows, each with its own color and timezone.
Reference Levels - individually toggle PDH, PDL, PDM, Daily Open and Weekly Open.
Reaction Logic - ATR length, touch tolerance in ATR, evaluation bars, label score filter, minimum label score, overlap reduction (bars and vertical ATR gap).
Visuals - show/hide reference levels, session dots, dots only on valid events, reaction zones, minimum score for zones, zone transparency and extension, live reaction zone, active reference band with its ATR size and transparency, active measurement highlight, level width, label size, label offset in ATR and label background transparency.
Panel - show/hide, position (six anchor points), Dark or Light theme, font size, optional guide row.
All numerical inputs carry professional English tooltips explaining their role, so the script can be tuned for any symbol, timeframe and trading style.
📘 HOW TO USE
1. Apply the script on an intraday timeframe. It is designed for intraday use and will stay passive on daily/higher timeframes.
2. Recommended starting timeframe is 4H for swing intraday context, and 1H for tactical intraday work. Lower timeframes (15m, 30m) work too but may produce dense output.
3. Start with the default settings. Observe which sessions and which reference levels generate the most Elite and Strong reactions on your symbol.
4. Use the panel to monitor the current state: last session, last reference, bias, score, tier, label filter, zone filter and the active reaction status.
5. Treat Elite (80+) and Strong (70-79) reactions as the main signals. Watch tier is informative and Weak tier is generally discarded.
6. Align with your own confluence: higher timeframe bias, structure, orderflow, or whatever your primary framework is. The script does not issue buy or sell calls - it scores reactions, and you decide.
⚠️ LIMITATIONS AND TRANSPARENCY
• This is not a strategy and does not place orders. No backtest statistics are implied.
• Reaction scores are computed after the evaluation window completes, so they are not repainting but are confirmed with a lag equal to the evaluation window size.
• The live reaction zone updates during the window and is finalized when the window closes.
• Session behavior varies significantly by symbol (crypto vs FX vs equities) and by volatility regime. Inputs should be tuned per symbol.
• Daily and Weekly references use standard request.security with barmerge.lookahead_off to avoid look-ahead bias.
• The script is not a forecasting tool. It is a post-event quantification of how price has just reacted to a known reference level.

ALN Sessions NQ 8am Prediction Model v3ALN Sessions — NQ Structural Framework
A structural analysis tool for NQ E-Mini Futures based on the Asia / London / New York overnight session relationships documented at nqstats.com.
All probability data is sourced directly from the 10-year study published at nqstats.com (2016–2026, n = 2,542 sessions). Full methodology and pattern breakdown available at: nqstats.com
What it does
At the 08:00 ET bar close (London session end), the indicator classifies the overnight structure into one of four patterns based on how the London range relates to the Asia range:
P1 - London Engulfs Asia (22% of sessions) — London expands beyond Asia on both sides. Symmetric two-way volatility into NY. No directional edge.
P2 - Asia Engulfs London (6.9%) — London compresses inside Asia. Strongest setup — NY broke at least one level in every session over 10 years.
P3 - Partial Engulf Up (41%) — London broke the Asia high but held the Asia low. Bullish overnight lean. High breaks in 80.8% of NY sessions.
P4 - Partial Engulf Down (30.2%) — London broke the Asia low but held the Asia high. Bearish overnight lean. Low breaks in 75% of NY sessions.
Features
Session boxes for Asia, London, and optional NY
London and Asia high/low levels extended into the NY session
Break probability labels on London Hi/Lo at the NY open
Previous day high/low lines with % distance
Live break detection labels when London levels are crossed
Conditional first-break edge display for P3 and P4 (the key edge degrades ~30pp if the wrong side breaks first)

Session Levels - Asia, London, NY, Premarket & Prior DayWhat it shows
session highs/lows for Asia, London, premarket, and the NY session during the RTH window; midnight open; NY RTH open and session close; optional NDOG 25% / 50% / 75% vs prior RTH close.
Prior day: completed RTH open, high, low, and close from the last RTH session, plus prior calendar day 24h high/low.
Untouched liquidity levels: optional highlight (color/line width) until the first qualifying wick/body intersection with the level (see inputs).
History: optional list of untouched levels from earlier days (subject to PulseWire line/label limits).
How to use
Set timezone and session strings to match your instrument (default: America/New_York). Enable or disable level groups and adjust colors under Levels and Colors.
Use "Untouched liquidity" to emphasize levels that have not yet been traded through per the script rules.
If you hit drawing limits, lower "Max untouched historical levels" or turn off historical untouched levels.
Limitations
Drawing count is capped by max_lines_count and max_labels_count. Very long history may require reducing stored historical levels or zooming to a shorter range.

Trading Sessions Suite [BackQuant]Trading Sessions Suite
Overview
Trading Sessions Suite is a full intraday structure framework built around market sessions, kill zones, and session-specific order flow . It transforms the trading day into a sequence of structured regimes, allowing you to track how liquidity, volatility, and positioning evolve across Asia, London, and New York.
Instead of treating price as a continuous stream, this indicator segments the market into time-based auction phases , each with its own:
Range (high and low)
VWAP (fair value)
Open (reference anchor)
Equilibrium (midpoint)
Momentum (session oscillator)
It also overlays kill zones , highlighting the exact windows where volatility and participation tend to expand.
Example of kill zones in action:
Example combining RSI-style oscillator + VWAP structure:
This tool is designed for traders who want to understand how intraday structure builds, shifts, and resolves .
---
Core Philosophy
Markets are not random throughout the day. Liquidity, volatility, and institutional participation are time-dependent .
Each session has distinct characteristics:
Asia → accumulation, compression, range-building
London → expansion, breakout, liquidity grabs
New York → continuation, distribution, reversal potential
Rather than using static indicators, this script builds a dynamic framework tied to these time regimes .
---
Session Engine
The indicator tracks three primary sessions:
Asia Session
London Session
New York Session
Each session is defined by a configurable time window and processed as an independent structure.
Internally, each session maintains a full state:
Session high and low
Session open
Rolling VWAP
Start index (session start)
Drawn objects (box, lines, labels)
Oscillator data (if enabled)
This allows each session to behave like a self-contained market environment .
---
Session Boxes (Auction Structure)
Each session is visualized as a box:
Top = session high
Bottom = session low
Width = duration of the session
This gives you an immediate view of:
Range expansion vs compression
Relative volatility between sessions
Where price is positioned within each session
Interpretation:
Tight box → compression, buildup
Wide box → expansion, active participation
Overlapping boxes → consolidation across sessions
---
Session VWAP (Fair Value per Session)
Each session has its own VWAP:
VWAP = volume-weighted average price within that session only
This is critical because:
VWAP resets every session
Reflects session-specific positioning
Acts as a dynamic equilibrium level
Interpretation:
Price above VWAP → bullish control for that session
Price below VWAP → bearish control
Reversion to VWAP → mean reversion inside session
Unlike standard VWAP, this gives you multiple fair value anchors per day .
---
Session Open & Midline (Key References)
Each session also tracks:
Open Line → where the session started
Midline → (high + low) / 2
These act as:
Bias indicators (above/below open)
Equilibrium zones (midline)
Reaction levels
Typical behavior:
Holding above open → trend continuation
Crossing midline → shift in control
Rejecting midline → continuation signal
---
Range Extension (Forward Liquidity Levels)
When a session closes, its high and low can be extended forward.
These extensions act as:
Future support/resistance
Liquidity targets
Breakout validation zones
Mechanically:
High and low are projected into the next session
Remain until replaced or invalidated
Interpretation:
Next session often trades toward previous session extremes
Breaks of prior session range = regime shift
---
Kill Zones (High-Probability Windows)
Kill zones are specific time windows inside sessions where:
Liquidity spikes
Volatility expands
Institutional activity increases
Included zones:
Asia Kill Zone
London Open Kill Zone
New York Open Kill Zone
New York Close Kill Zone
They are visualized as shaded boxes separate from session boxes.
Why they matter:
Most breakouts occur during kill zones
Most reversals are initiated during kill zones
Liquidity sweeps cluster around these times
From the example:
You can see how price reacts specifically within these windows.
---
Session Oscillator (Embedded Momentum Engine)
Each session optionally includes its own oscillator plotted directly below the session box.
This is not a standard indicator overlay. It is:
Bound to the session range
Scaled relative to that session
Reset each session
Core mechanics:
Uses RSI-style calculation
Signal line = moving average of oscillator
Stored per bar within the session
Displayed as:
A mini panel under each session
With 30 / 50 / 70 reference levels
Example:
Interpretation:
Above 50 → bullish momentum within session
Below 50 → bearish momentum
30/70 → oversold/overbought zones
This gives you contextual momentum , not global momentum.
---
Why Session-Based Oscillators Matter
Standard oscillators ignore time segmentation.
This approach:
Resets momentum every session
Prevents carryover noise
Aligns signals with actual trading windows
So instead of:
“RSI is overbought”
You get:
“RSI is overbought within London session”
This is a much stronger contextual signal.
---
Labels & Range Statistics
Each session can display:
Session name (ASIA, LON, NY)
Range percentage
This helps quantify:
How much the market moved during that session
Which session is dominating volatility
---
Putting It All Together
This indicator gives you a full intraday map:
Where price moved (session boxes)
Where fair value sits (VWAP)
Where equilibrium lies (midline)
Where momentum stands (oscillator)
Where volatility expands (kill zones)
Where liquidity rests (extended highs/lows)
---
How to Use It
1) Identify the current session
Always start with:
Which session is active?
Each session behaves differently.
---
2) Use VWAP + midline for bias
Above VWAP + above mid → strong trend
Below VWAP + below mid → bearish control
Between → range
---
3) Watch kill zones for setups
Breakouts during kill zones are higher probability
Fake moves often occur just before them
---
4) Track previous session levels
Asia high/low often targeted during London
London extremes often targeted during NY
---
5) Use oscillator for confirmation
Momentum aligning with structure → stronger signal
Divergence → potential reversal
---
Strengths
Fully contextual intraday framework
Combines time, price, and volume-weighted logic
Visual and intuitive
Highly configurable
---
Summary
Trading Sessions Suite converts the trading day into a structured sequence of auctions. By combining session ranges, VWAP, kill zones, and a session-specific momentum engine, it provides a complete framework for understanding how price moves throughout the day. Instead of relying on static indicators, it aligns analysis with when liquidity actually enters the market, allowing for more precise timing, better context, and cleaner trade execution. Indicator
AG Pro Kill Zone Session Engine [AGPro Series]AG Pro Kill Zone Session Engine
Overview / What it does
AG Pro Kill Zone Session Engine is a session-based overlay designed to map the internal range behavior of selected intraday kill zones and preserve the most relevant reference levels after each zone has ended.
Instead of treating London, New York, Asia, and London Close as simple background highlights, this script organizes each enabled zone as a structured session event. During an active zone, it tracks the developing high, low, and optional midpoint. After the zone closes, it can carry those levels forward as clean horizontal references so traders can study how price interacts with prior session liquidity.
The script is built for users who want more context than a basic session coloring tool. It helps visualize where a session range formed, how wide it was relative to recent history, whether the session expanded or stayed narrow, and whether later price action interacted with that session through sweep-style behavior.
This is not a prediction engine and it does not attempt to forecast the next directional move. Its purpose is to structure session information into a cleaner analytical framework so traders can evaluate intraday context with more consistency.
Unique Edge
What makes this script different from a standard session indicator is that it does not stop at showing when a session is active.
Its core focus is session range formation plus post-session interaction. Each enabled kill zone can build a live range while active, then leave behind reference levels that remain usable after the session ends. This allows the chart to show not only where a session occurred, but also how later price responded to that session.
The script also adds session-width context. A zone can be classified relative to recent comparable zones so traders can quickly see whether the session was narrow, balanced, or expanded. That extra layer helps separate passive session activity from zones that created a more meaningful range.
Another important distinction is the sweep engine. Rather than only drawing static levels, the script can evaluate whether later price action interacts with prior session highs or lows in a sweep-oriented manner. This makes the tool more useful for traders who study liquidity behavior around specific intraday windows.
In short, this script is intended to function as a session behavior map, not as a simple background painter.
Methodology
The script works in four main steps.
1) Session detection
The user can enable or disable the supported kill zones individually and define session windows using a UTC offset and custom time settings. This keeps the script flexible across instruments, broker feeds, and local chart preferences.
2) Range construction
While a kill zone is active, the script updates the developing session high and low. Optional midpoint logic can also be shown. These values form the core session range for that specific zone.
3) Post-session reference mapping
When the zone ends, the completed high and low can remain on the chart as forward reference levels. This allows later price interaction to be evaluated against a completed session range rather than only during the active zone itself.
4) Sweep and width analysis
The script can evaluate reference-level interactions using its sweep logic and can also classify the completed width of a zone relative to prior zones of the same type. This helps the user distinguish between narrow, balanced, and expanded sessions.
Signals & Alerts
This script is primarily an analytical overlay, but it also supports alertable events around session activity and sweep behavior.
Depending on the enabled options, the script can be used to monitor:
- when a new kill zone becomes active,
- when price interacts with a prior session high,
- when price interacts with a prior session low,
- when sweep-oriented behavior is detected relative to a carried-forward reference range.
These events are designed to describe chart conditions, not to deliver standalone trade calls.
The visual outputs can include:
- session background shading,
- current and completed session high/low levels,
- optional midpoint levels,
- compact session summary labels,
- sweep markers,
- an information panel showing active zone status, width context, reference zone, and sweep status.
Key Inputs
The script includes a focused but flexible input set so users can adapt it without overcomplicating the chart.
Core controls include:
- UTC offset and custom session timing,
- individual enable/disable controls for Asia, London, New York, and London Close,
- high/low visibility,
- midpoint visibility,
- projection length for completed session levels,
- label density and summary behavior,
- panel visibility, placement, and text sizing,
- sweep mode and alert controls,
- visible session memory so the chart can stay cleaner on higher timeframes.
These controls allow the tool to be used in a more detailed mode on lower intraday charts or in a more compressed mode on higher timeframes.
Limitations & Transparency
This script is designed as a context tool. It does not define trade entries, stop placement, or risk management for the user.
Session behavior can vary across instruments and feeds, so identical settings may not produce equally meaningful output on every market. Some assets respond more clearly to session-based reference levels than others.
Sweep logic is also a chart-interpretation aid, not a certainty model. A detected sweep does not imply immediate reversal, continuation, or trade validity on its own. It simply highlights a specific type of interaction with a prior session reference.
The script is best suited to intraday analysis. While it can still display useful information on higher timeframes, the underlying logic is rooted in session behavior, so lower intraday charts will usually provide more direct visual relevance.
As with any visual overlay, increasing history depth or label density may add chart clutter. For that reason, the script includes controls to compress memory and reduce label load when needed.
Risk Disclosure
This script is provided for educational and analytical use only.
It is not financial advice, not a signal service, and not a promise of outcome. It does not guarantee reversals, breakouts, continuations, or profitable execution. Any trading decision should be made within the user's own process, risk model, and market understanding.
The intended use of this script is to help organize session structure, liquidity references, and post-session interaction on the chart so that traders can make more informed observations with a clearer visual framework.
Indicator
Indicator
Midnight OpenThis Midnight open indicator tracks and displays each trading day’s midnight open based on a user-selected time zone. It lets the user choose between America/New_York, the chart’s exchange time zone, UTC, GMT, or a custom GMT/UTC hour offset, then detects when midnight occurs in that time zone and captures the open price either from the chart timeframe or from a 1-minute source for better precision. It filters by trading-week mode, so the script can operate on standard Monday–Friday schedules, Sunday–Thursday futures-style weeks, or all calendar days. Once a valid midnight open is found, it plots the current day’s level as a step line on the chart and can also draw a separate horizontal line for each day, with optional labels showing the weekday, 00:00 time stamp, and active time zone.
The Midnight Open indicator also keeps a rolling weekday dashboard that stores the latest Monday through Friday midnight open values and shows them in a table in the chart corner, with the active time zone included in the table header. Those table values are formatted with comma-separated numbers while preserving the instrument’s tick precision. To keep the chart clean, the script automatically limits how many historical lines and labels remain visible based on a user-defined lookback count. In addition, it generates a “new midnight open” event when a fresh daily level is captured and can fire a dynamic alert message that includes the active time zone, symbol, and timeframe, making it easier to monitor midnight reference levels across different markets and time zone settings.

Sessions ExtendedSessions Extended
Based on the original "Sessions" indicator by LuxAlgo, this script is a complete
rewrite and substantial expansion. It is built for traders who want control
over session visualization, deep volume analytics, and a live dashboard that works
on any chart timeframe from 1 minute up to 1 week.
=============================================================================
WHAT CHANGED COMPARED TO THE ORIGINAL "SESSIONS" INDICATOR
=============================================================================
SESSIONS
Original: 4 fixed sessions (New York, London, Tokyo, Sydney)
Extended: 11 fully independent sessions labeled A through K, each with its own
complete settings group. The default setup covers the major forex windows:
Asia, London, New York, Sydney, Tokyo I, Hong Kong, Singapore I, Tokyo II,
Singapore II, EU pre-London, and US pre-NY.
PER-SESSION STYLING
Original: One shared background color and transparency, border always dotted,
no width control.
Extended: Per-session background color and transparency, fully independent of
the border color. Per-session border style (Dotted / Dashed / Solid) and border
width (1 to 4 pixels). Every session box can have a completely unique appearance.
SESSION LABELS
Original: One fixed label per session, always tiny, always at the session high.
Extended: Per-session label color and size (Tiny / Small / Normal / Large / Huge).
A numeric "Name Offset" input shifts the label upward by a chosen number of
blank lines, keeping label height constant regardless of zoom level. An optional
second label shows the actual session open and close times in HH:mm format with
its own independent offset, color, and size.
OVERLAYS PER SESSION
Each of the 11 sessions independently supports seven overlay types:
Range Box — High/Low box drawn for each session occurrence
Trendline — Linear regression line (best-fit straight line through closes)
Std Band — Dashed lines at +1σ and -1σ around the regression line.
Works independently — Trendline does not need to be active.
Bars outside the bands indicate unusual price movement.
Mean — Cumulative average of all closing prices within the session,
drawn as a connected line. Equal weight per bar, no volume
influence. See "Understanding Mean vs VWAP" below.
VWAP — Volume-Weighted Average Price. Institutional benchmark.
See "Understanding Mean vs VWAP" below.
Max/Min — Short horizontal tick marks at session High and Low
Midpoint — Horizontal line at the 50% level of the session High/Low range
EXTENDED HIGH/LOW LINES
Each session can project its previous High and Low as horizontal lines extending
to the right of the chart — classic support and resistance reference levels.
Fully configurable per session:
- Line color (independent from the session border color)
- Line style: Solid, Dashed, or Dotted
- Line width: 1 to 4 pixels
- Optional end-of-line label showing session name and date (dd.MM.yy)
- Label text color, background color, and background transparency
A global "Max Extended H/L Lines" setting (Range Settings group, default 10)
caps the total number of line pairs visible across all sessions combined.
DAYS BACK FILTER
Each session has a "Last N sessions" input. When set to 0 (default), all
available history is shown. When set to 1–50, only the N most recent occurrences
are drawn. The pruning applies consistently to boxes, labels, Max/Min lines,
Midpoint lines, Mean lines, VWAP plots, and Extended H/L lines.
TIMEZONE
A "Use Exchange Timezone" checkbox follows the exchange timezone automatically
(syminfo.timezone). When unchecked, a UTC Offset field (−12 to +14) enables
manual adjustment. This is particularly useful for handling Daylight Saving Time
transitions without needing to touch any session time strings.
=============================================================================
THE DASHBOARD — COMPLETE REFERENCE
=============================================================================
ENABLING AND POSITIONING
Find the Dashboard group in Settings. Toggle "Show Dashboard" to show or hide
the panel. Choose from four positions (Top Left, Top Right, Bottom Left,
Bottom Right) and four sizes (Tiny, Small, Normal, Large).
DASHBOARD MODES
The dashboard has three display modes, selected via the "Volume & Sigma columns"
and "Show Buy/Sell Volume" toggles:
Standard mode (both off):
Session | Trend
Advanced mode (Volume & Sigma on):
Session | Volume | Sigma | Trend
Advanced + Buy/Sell mode (both on):
Session | Volume | Sigma | ▲Buy ▼Sell | Trend
COLUMN DESCRIPTIONS
Session
The session name (e.g. ASIA, LONDON, NEW YORK). The cell background
changes color to reflect the session state:
Active background color — session currently open
Inactive background color — session closed today (snapshot visible)
Dimmed border color — session not yet started today or yesterday data
Volume
Total traded volume for the session's measurement window. Updates live
while the session is open. Freezes as a snapshot when it closes.
Calculated at 1-minute resolution via request.security — accurate on
any chart timeframe.
Sigma (σ)
Standard deviation of closing prices within the session. Measures how
much price spread around its average. A high Sigma indicates a volatile,
wide-ranging session. A low Sigma indicates tight, consolidating price
action. Updates live, freezes on session close.
▲Buy ▼Sell (optional, "Show Buy/Sell Volume")
Volume split by bar direction. Up-bars (Close ≥ Open) count as buy volume,
down-bars count as sell. Note: this is an approximation — Pine Script
cannot access PulseWire's internal tick-level buy/sell data.
Open / High / Low (optional, "Show O/H/L + Change")
The session's opening price, highest traded price, and lowest traded price.
These are permanent historical facts and remain visible (dimmed) even after
the session closes and after the trading day resets.
Chg (optional, "Show O/H/L + Change")
The change from session Open to session Close: Close − Open.
Display format:
+1.234 green — session closed above its open (bullish)
-1.234 red — session closed below its open (bearish)
±0.000 grey — session closed exactly at its open (neutral)
The three colors (up, down, flat) are independently configurable.
Trend (r²)
The R-squared value of the linear regression for the session. Ranges from
−1.00 to +1.00. Positive values indicate an upward trend, negative values
a downward trend. Values near 0 indicate a sideways/choppy session.
The cell background is colored green (bullish) or red (bearish) based on
the sign, making trend direction scannable at a glance.
Timer (optional, "Show Timer column")
Countdown to the next relevant session event:
▼ HH:MM — session is currently open, counting down to close
▲ HH:MM — session is closed, counting up to next open
▲ Xd HH:MM — session opens in more than 24 hours (e.g. weekend gap)
The timer is updated in real time using timenow. It is visible at all
times, including when the market is closed. Weekend gaps are handled
correctly: sessions that open Monday morning show 2d+ on Friday evening,
while sessions still opening later on Friday show the same-day countdown.
The timer text is colored with the active session color when open, or
dimmed when the session is waiting to open.
DAY TOTAL ROW
When one or more sessions have "In Day Total" checked in their settings,
a Day Total row appears at the bottom of the dashboard. It shows:
- The sum of all Volume values from today's In-Day-Total sessions
- The average Sigma across those sessions
Critically , Day Total counts only sessions that have actually run since the
last anchor-session reset — not yesterday's data. If ASIA (the default anchor)
opened at 18:00 EST and New York has not yet run today, New York's data from
the previous day will appear in its row (dimmed) but will not be included in
Day Total.
YESTERDAY ROW
When all sessions have closed, a Yesterday row appears showing the prior
trading day's totals for comparison. This row disappears once the new
trading day begins.
STALE DATA — THREE BRIGHTNESS LEVELS
The dashboard uses text brightness to communicate data age at a glance:
Full brightness — session is currently active (live data)
Dimmed — session ran and closed today (today's snapshot)
More dimmed — session has data from the previous day (no run today yet)
Near-invisible — session has no data at all (never run or newly enabled)
The dim percentage is configurable ("Stale data text dim", 0–90%).
RESET LOGIC — HOW THE TRADING DAY IS DEFINED
The dashboard needs to know when a new trading day begins. This is controlled
by "Reset Stats when Session starts" in the Dashboard group (default: A = ASIA).
When the selected anchor session opens:
- All "ran today" tracking flags are cleared
- Day Total recalculates from zero
- Sessions not yet run show their previous data dimmed until they run again
Snapshot data inside each session's measurement function persists until the
session runs again and overwrites it. This means US pre-NY data from 08:30
yesterday is still visible in the dashboard at 04:00 today, correctly dimmed,
and correctly excluded from Day Total.
VOLUME MEASUREMENT WINDOW
Each session has a separate "Vol window" session input. By default this matches
the display session, but you can narrow it. For example, you could display the
full 18-hour ASIA box but only measure volume for the first two hours of
activity. The Vol window does not affect the displayed box or overlays —
it only affects Volume, Sigma, Buy/Sell, and Trend statistics.
DASHBOARD COLORS (configurable)
Active cell background — highlight color for currently open sessions
Inactive cell background — color for closed sessions with today's data
Text color — all non-highlighted cell text
Border color — table grid lines

UNDERSTANDING MEAN vs VWAP
=============================================================================
Mean is the simple average of all closing prices within the session:
(Close₁ + Close₂ + ... + Closeₙ) / N
Every bar contributes equally regardless of how much was traded. Mean shows
the geometric center of price over time — a neutral, unweighted reference.
VWAP (Volume Weighted Average Price):
Σ(Close × Volume) / Σ(Volume)
Bars with high volume pull the VWAP toward them. Institutions use VWAP as
the primary benchmark for execution quality. A price above VWAP signals that
the session is running bullish on a volume-weighted basis; below is bearish.
The practical difference: when a sharp directional move occurs on thin volume,
Mean shifts significantly because it counts each bar equally. VWAP barely
reacts because little volume participated in the move. This divergence — Mean
far from VWAP — can itself be a signal that the move lacks conviction.

All times are in UTC-5 (New York EST). Adjust the UTC Offset setting or enable
"Use Exchange Timezone" to match your local time.
Sessions H through K are disabled by default. Enable them in their respective
settings group. Note that newly enabled sessions will show no data until
they have run at least once after being activated.
=============================================================================
SETUP GUIDE — GETTING STARTED
=============================================================================
Step 1 — Timezone
Open Settings → Timezone. If your instrument uses the exchange timezone
natively, enable "Use Exchange Timezone". Otherwise set UTC Offset to your
local offset (e.g. -5 for New York EST, +1 for Berlin CET). If your region
uses DST and PulseWire does not adjust automatically, update this offset
manually at DST transitions.
Step 2 — Sessions
Sessions A (ASIA), B (LONDON), and C (NEW YORK) are enabled by default with
commonly used forex hours. Adjust the session time strings to match your
instrument's actual active hours. Enable additional sessions (D through K) as
needed from their settings groups.
Step 3 — Dashboard
Open Settings → Dashboard. Enable "Show Dashboard". Choose your preferred
position and size. Enable "Volume & Sigma columns" for full statistics.
Enable "Show Timer column" to see live countdowns. Configure which sessions
should contribute to Day Total via the "In Day Total" checkbox in each
session's group.
Step 4 — Overlays
For each session you want to analyze deeply, enable the overlays relevant
to your strategy. Recommended starting set: Range Box (always on), VWAP for
institutional context, Mean for a price-weighted counterpart, Std Band for
volatility context.
Step 5 — Extended H/L Lines
Enable "Ext H/L" in any session group to project that session's previous
High and Low forward as S/R references. Set "Max Extended H/L Lines" in
Range Settings to a comfortable number (default: 10 pairs total).
Step 6 — Days Back
If your chart history is long and performance is slow, set "Last N sessions"
in each session group to limit how many occurrences are drawn (e.g. 5 to 20).
=============================================================================
ALERTS
=============================================================================
22 alert conditions are available — one "Session Start" and one "Session End"
for each of the 11 sessions. Alerts fire only when the corresponding session's
"Show" toggle is enabled. Set alerts via the Add Alert dialog in PulseWire,
selecting this indicator from the condition dropdown.
=============================================================================
LIMITATIONS AND KNOWN BEHAVIOR
=============================================================================
Buy/Sell volume approximation
Up-bar (Close ≥ Open) = Buy volume. Down-bar = Sell volume. True tick-level
data is not accessible in Pine Script. Treat this column as directional
sentiment, not precise order flow.
Initial load time
11 request.security calls at 1-minute resolution cause a delay when first
applying the indicator to a chart with long history. This is a Pine Script
constraint — the 1m resolution is required for accuracy on higher timeframes.
request.security usage
This script uses 12 of Pine Script's 40 allowed request.security calls
(11 session functions + 1 anchor-reset detector), leaving 28 available
if you build on top of this script.
Short sessions on high timeframes
Sessions shorter than the chart's bar duration (e.g. a 30-minute session on
a 4H chart) may not be detected. Use a lower timeframe for short sessions.
Timer and market holidays
The countdown timer uses calendar arithmetic, not an exchange trading calendar.
On public holidays the timer will count down to the session time as if it
were a normal trading day. Weekend detection (Friday evening, Saturday) is
handled correctly for standard Mon–Fri market hours.
Dashboard layout
Table positions are limited to the four corners as defined by Pine Script's
table API. Sub-corner pixel positioning is not supported.
