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.

AlgoStorm Institutional Session Structure (ISS)AlgoStorm Institutional Session Structure (ISS)
A complete intraday auction-structure engine that maps global session boxes (Asia, London, New York), the Globex overnight range, the Initial Balance with day-type extension targets, the Opening Range, and an automated overnight-inventory classification of the RTH open — directly onto your intraday charts.
The AlgoStorm Institutional Session Structure (ISS) indicator is designed for index futures and intraday traders who read the market through the auction lens: where overnight inventory built, whether the open printed inside or outside that inventory, whether the Initial Balance is containing rotation or the day is extending toward trend, and which session built the reference high or low everyone now trades against. It answers those questions structurally instead of drawing decorative boxes.
TIMEFRAME REQUIREMENT — READ BEFORE LOADING
This is an intraday tool. It refuses to run on 1D charts and above, and the chart timeframe should stay at or below the Opening Range length (the Opening Range and Initial Balance locks resolve at bar granularity). All session windows are DST-aware through a configurable IANA timezone, defaulting to New York time.
Technical Architecture: Fixed-Pool Session Engine
Session-structure indicators commonly rebuild their drawings on every bar, bloating chart performance and churning objects. ISS uses a different execution model:
Per-Session Box Engines: Each session runs its own tracking engine with a private box history. The active box updates its high/low boundary in place as the session develops; boxes older than the history cap (default five days, configurable to twenty) are evicted automatically.
Time-Window Lock Pipeline: The overnight range, Initial Balance, and Opening Range each accumulate in staging registers, then lock permanently the moment their window closes — the overnight at the RTH open, the IB and OR when their configurable minute-windows complete. Locked levels cannot move for the rest of the day.
Extension Mathematics: Extension targets use the classic day-type formula, extension(m) = IB low + m × IB range above the market and IB high − m × IB range below it, with 1.5× and 2.0× defaults. A 1.5× tag means price has traveled 150% of the IB range from the opposite IB boundary.
Zero-Churn Drawing Pool: Every level line and label is created exactly once at initialization and repositioned in place afterward. No per-bar create/delete cycles, no garbage-collection artifacts.
Label Anti-Overlap Engine: Right-edge labels (ON, IB, extensions, OR) are sorted by price each bar and automatically spaced apart whenever two or more sit within a configurable minimum gap (default 0.05% of price). Level lines always stay locked to the true price — only the label text position shifts to stay readable. On by default; fully optional.
Confirmed-Bar Alert Gate: Every alert condition is gated on confirmed bar closes inside RTH. Nothing repaints, and no alert can fire intra-bar and then vanish.
Features & Functionality
Session Boxes: Asia, London, and New York boxes with running high/low, dotted session-open line, and session label. Defaults cover the full sessions (18:00–03:00, 03:00–09:30, 09:30–16:00 New York time); killzone-style alternatives are documented in the input tooltips.
Overnight Range Lock: Globex high/low accumulated through the overnight window and held through the trading day — the reference frame for gap and inventory reads.
Initial Balance + Extension Targets: First 60 minutes of RTH (configurable 15–120) with configurable extension multiples for day-type classification: containment inside the IB, 1.5× tests, or 2× trend extension.
Opening Range: First 15 minutes of RTH (configurable 1–60) — the breakout reference for the open drive.
Overnight Inventory Read: At the RTH open, the engine classifies the print: above the ON high, upper half of the ON range, lower half, or below the ON low — the gap-risk context before the first rotation completes.
Session State Table: Active session, ON high/low, open-vs-ON classification, IB range (shows "forming…" while building, then the locked H/L) with a separate breakout status (inside IB vs. breakout ▲/▼), OR range and status, and which IB extensions have been tested — the whole auction state in one glance.
Alert Suite: Eight conditions — Opening Range breakout up/down, Initial Balance breakout up/down, overnight high/low break, and upper/lower reach of the second IB extension multiple (default 2.0×, trend-day behavior). The first multiple (default 1.5×) is tracked live in the state table but does not carry its own alert.
Honest limitations: ISS is structural context, not a signal system — no entries, no exits, no arrows . Intraday levels draw for the current day only by design; historical context comes from the session boxes. If you also run our Institutional Key Levels (IKL) script, keep IKL's Initial Balance, Opening Range, and Overnight toggles off so nothing double-plots — ISS is the time-anchored view, IKL is the right-edge level strip.

Zero Noise KillzonesThe Killzones, outlined. Nothing else. The ICT killzones drawn cleanly, with each one's high and low carried forward as levels.
What it does
- Outlines the killzones: Asia (20:00–00:00), London (02:00–05:00), New York AM (09:30–11:00), New York Lunch (12:00–13:00, off by default), and New York PM (13:30–16:00) — all pinned to New York time, so daylight-saving changes are handled automatically on any chart, in any timezone.
- A separate forex set — Asia, London Open, New York Open (07:00–10:00), London Close (10:00–12:00) — off by default, so forex traders have the complete set in one place. NY AM and NY Open overlap by design: different windows that share 30 minutes.
- When a killzone closes, its high and low carry forward as levels. A level stays lit and keeps extending until price trades through it — then it greys out and stops. A sweep counts on the wick: any trade through the level retires it, even if the candle closes back inside. A wick through a level is information — that's the definition, on purpose.
- Days Kept bounds how long anything lives on the chart. Nothing accumulates forever.
- Custom windows: up to seven of your own sessions, any HHMM–HHMM window (midnight wraps handled), in any timezone.
What it deliberately doesn't do
- No signals, no alerts, no arrows — a deliberate omission in the free tools, not an oversight. A killzone high is context, not a trade call. The trade is yours.
Settings
- Killzones: five futures windows plus the four-window forex set, each an independent toggle
- Extend Highs & Lows: Until Swept (levels carry forward) or Session End (outlines only)
- Custom: timezone + up to seven custom windows
- Theme: Auto / Dark / Light — change any swatch and your color wins on every theme
- Line width, fill, tags, Days Kept (1–5), watermark — all optional
Futures, stocks, and FX, on any intraday chart up to 1h — above 5m, windows are rebuilt from 1-minute data for exact alignment.

Session Liquidity Architecture [MQLSoftware]Session Liquidity Architecture reads the trading day as a repeating structure of sessions — and instead of restating fixed session folklore, it measures how the instrument on your chart actually behaves inside that structure.
Most session tools draw boxes and stop there. This indicator adds three algorithmic elements on top of the session-box base, and every number it prints is derived from the chart's own history.
Key Features
Self-calibrating session range model — every completed session range is ranked as a percentile of that session's own trailing distribution. The active session shows a live read: current range, % of its median, and the percentile it has already reached. No pip or point thresholds, no magic numbers — the model adapts to any symbol and timeframe by construction.
Session liquidity state machine — each session's High and Low arm at session close and are then tracked through explicit states: armed → swept → rejected or accepted. A sweep is only registered on a confirmed bar; the rejection read compares the sweep bar's close against the level. Levels that survive until the next same-session open are marked expired.
Measured base rates — the panel reports observed frequencies from the loaded history: how often London actually sweeps the Asia High or Low on this chart, how often New York sweeps the London extremes, and how often price closes back inside after each sweep. These are counted events with the sample size shown (n), not assumptions — and below a minimum sample the panel says "collecting" instead of quoting a percentage.
Three configurable sessions (Asia, London, New York) with per-session IANA timezones, so daylight-saving shifts are handled automatically.
Previous Day High / Low tracked through the same armed → swept state machine.
Day separators, per-session colors, and a compact statistics panel.
Core Concept — what is original here
Session boxes are common. The original contribution of this script is that it treats the session map as a measurement problem :
1. Percentile-ranked session ranges. A "big" or "quiet" session is only meaningful relative to that session's own recent distribution. Ranking the live range against the last N completed ranges of the same session produces a self-calibrating expansion read that works identically on FX majors, indices, or crypto — without any instrument-specific settings.
2. A liquidity state machine instead of static lines. Session extremes are treated as objects with a lifecycle (armed, swept, rejected/accepted, expired). Because state transitions happen only on confirmed bars, the sweep history you see on the chart is exactly the history the statistics are built from.
3. Base rates instead of narratives. The common claims about session behavior ("London takes out the Asia range", "the sweep reverses") become testable numbers here. A counted event is strictly defined: a sweep is the first confirmed-bar break of an armed level while the later session is active, and it counts as "rejected" when the sweep bar closes back inside the level. On some instruments the measured frequencies are strongly asymmetric; on others (for example 24/7 crypto) they hover near a coin flip — and the panel will honestly show you that. The point is to replace assumption with measurement on the exact chart you trade.
Anatomy of the Display
Session boxes — one box per session per day, labelled with the session name; completed boxes append the final range and its percentile (e.g. "LONDON 0.00421 · P63").
Level lines — each session's High/Low extends right from the moment it arms at session close. A red ✕ mark shows where it was swept. Untouched levels turn dotted when they expire at the next same-session open.
PDH / PDL — dashed lines for the previous day's extremes, same sweep marking.
Statistics panel — one row per session (live or last range + percentile, and the state of its levels; states shown during a live session are prefixed "prev" because they belong to the previous cycle), followed by the measured base-rate block with sample sizes.
Notes on Repainting
Sweep events, rejection reads, base-rate counters and all alerts fire on confirmed bars only and do not repaint.
Session boxes, the live range and the live percentile update intrabar while a session is open — they are visual context for the current session, not signals.
No security() calls, no lookahead: everything is computed from the chart's own bars.
Boxes and level lines are drawing objects anchored to past bars by design (a session box spans its session, a level line starts at the bar of the extreme). This affects only how history is displayed, never the event logic.
Typical Analysis Workflow
Check the panel: how much of its typical range has the active session already used? A session at 40% of median is quiet by its own history; one at P90 has already been unusually wide for that session. These numbers describe the distribution so far — they do not predict what the next bar will do.
Watch the armed levels from the prior session and the previous day: they are the objective reference points the state machine is tracking.
When a sweep prints, read the rejection/acceptance tag and compare it with the measured base rate for that exact scenario on this chart.
Configuration
Session hours and timezone per session (defaults: Tokyo 09:00–18:00 JST, London 08:00–17:00 UK, New York 09:30–16:00 ET). Futures/FX traders can widen them or repurpose a slot as a killzone.
Rendering depth, box transparency, day separators, PDH/PDL on/off.
Sweep marks: Minimal (small ✕ text) or Pill, and how many days of marks to keep.
Stats lookback (sessions) for the percentile model; panel position and text size.
Markets and Timeframes
Intraday timeframes only (the script tells you if the chart is not intraday). Best readability from 5m to 1h. Works on FX, indices, futures, stocks and crypto — on 24/7 markets the session definitions matter more than the defaults, so adjust the hours to your venue.
Alerts
Liquidity swept — any session extreme or PDH/PDL taken (confirmed bar). The alert() message names the exact level and outcome, e.g. "EURUSD 60 — liquidity swept: ASIA H (rejected)".
Session range expansion — the active session crossed the 80th percentile of its own history.

Sessions + Killzones [HermesCore]WHAT THIS INDICATOR DOES
Sessions + Killzones tracks the three desk sessions: Asia, London and New York, plus an optional custom window. While a session is open you see it as a live box. When it closes, its high and low become levels. Each level gets a simple 0 to 6 quality score, and from then on the script tracks what price does with it: swept, run, or held.
Every outcome feeds a statistics engine. It answers the core question of this script: what does the next session usually do with the levels of the previous one? Measured on your own chart, with sample sizes shown.
Killzones are the windows where institutional activity concentrates, around the desk opens. They render as background shading, set in New York time per ICT convention (Inner Circle Trader, the school this session vocabulary comes from). The dashboard shows which session and which killzone are active right now, each with a countdown. It also covers the daily window where nothing is open. I gave that window a name: the Dead Zone.
WHY IT IS DIFFERENT
Most session indicators draw boxes and stop. The few that score sessions usually hide how the score works. My rules are:
- A level gets its score at birth and the score never changes. It is built only from facts about how the session formed: range, volume, how clean the extreme was, and confluence with key levels. What happens later is shown by the lifecycle markings, not by changing the score.
- A sweep and a run are two different events. A wick beyond the level that closes back inside is a sweep. That is information: stops were taken and price came back. A close beyond the level plus a 0.1 ATR buffer (Average True Range, a standard volatility measure) is a run. The level is consumed.
- The statistics are counted honestly. A pair like "AS.H in LDN" only counts what happens while London is actually open. Levels that die before their judging session opens are not counted at all. The dashboard shows the n for every pair, so you always see how much evidence sits behind a percentage.
- Sessions are boxes, because their range matters: it becomes levels. Killzones are background shading, because only their timing matters. Two layers, two visual languages.
- Everything updates on confirmed bars only. No intrabar flicker. No levels that appear and disappear within the same candle.
HOW TO READ THE CHART
- Live session box: bright, thick border, session tag in the corner. Closed boxes fade into quiet history.
- Session levels: horizontal lines starting at the bar that set the extreme. A label like "LDN.H A S:5" reads: London session high, grade A, score 5. The abbreviations: AS is Asia, LDN is London, NY is New York, .H is the high, .L is the low.
- Gold color with a soft glow and larger text: the grade is A or S. Those are the premium sessions.
- Thick border on a level: it was swept. The label gets a "swept" suffix.
- Grey line without text: the level was run. It stays as quiet history, or you can have runs deleted.
- Levels expire when the next session of the same type closes. Yesterday's Asia high stops mattering once today's Asia delivers a fresh one.
- Killzone shading: vertical background bands for Asia, London, NY AM, and optionally London Close. All set in New York time.
- Dotted horizontal line: the midnight open at 00:00 New York.
- Dotted vertical lines to the right of price: the projected next open of each session, in session color. The chart version of the dashboard countdown. They respect the Weekdays Only filter.
- Neutral horizontal lines: previous day high and low (PDH, PDL) and previous week high and low (PWH, PWL), always from the last completed day and week. When a daily and a weekly level are equal they merge into one line with a combined label.
- Session midlines (CE, consequent encroachment, simply the middle of the range): dotted at the middle of each closed session, turning solid gold with a label like "AS CE" on the first touch. On by default.
- Killzone range lines: when a killzone closes, its high and low freeze as dashed lines in the killzone color. They carry no score, no lifecycle and no statistics. They are pure context and expire when the next killzone of the same type closes. On by default.
THE SCORE
Every component is measured at session close against the average of the last 20 sessions of the same type. Asia is always compared with Asia, London with London.
- Range: the session range is more than 1.2x its own average, +2
- Volume: the session volume is above its own average, +2
- Clean extreme: the high or low was set in the first half of the session and never revisited within 0.1 ATR, +1
- Key confluence: the level lies within 0.25 ATR of PDH, PDL, PWH or PWL, +1
Grades: S (6), A (5), B (4), C (3), D (0 to 2). There is no strength filter on purpose. A day produces at most six levels, which is scarce enough to show them all and let the grade speak.
SEQUENCE STATISTICS
Six pairs, following the natural hand-off: Asia levels are judged by London, London levels by New York, New York levels by the next Asia. For each pair the dashboard shows the swept share, run share, held share, and n, the number of judged levels behind those percentages. Held means the judging session closed without resolving the level. The optional custom session gets the full level lifecycle but stays out of these statistics.
This is regime information. If "AS.H in LDN" shows 36 percent swept while the lifetime base is 45, London is currently respecting Asia highs more than usual. An alert can warn you when a pair crosses 70 percent swept.
THE DEAD ZONE
Between the New York close and the Asia open, nothing is open. I named that window the Dead Zone, and it does real work here. Liquidity is thinnest there. A New York level that gets run inside the Dead Zone disappears before Asia ever gets to judge it. That is why the New York pairs always show a smaller n: n only counts levels that survived until their judging session opened. The dashboard names the Dead Zone when you are in it and counts down to the next open. Neutral shading, on by default, makes it visible on the chart. It is defined as "no session live", so it stays correct through every daylight saving (DST) change, and with Weekdays Only on, the whole weekend becomes one long Dead Zone.
DASHBOARD
Session now with a closing countdown, or Dead Zone with an opening countdown. Range and volume of each session against its own average, live sessions marked. The six pairs with percentages and n. Active level count, the lifetime swept versus run ratio, and Killzone now with its own countdown. Heat bars are proportional everywhere.
HOW I USE IT
My preferred timeframes, in order:
- 15m is the home base. Sessions are 30 plus bars wide, so the clean extreme component means something. The 09:30 New York open lands exactly on a bar. And the chart loads the most history, which gives the statistics their highest n.
- 5m is the execution frame. Sweeps and runs resolve on bar closes, so 5m shows the fight around a level in finer detail, and killzones become readable blocks. The cost is sample size: the statistics run on roughly a third of the history, so I treat those percentages as indicative and keep the regime read on 15m.
- 1h works but is the edge case. Hourly bars cut off the 09:30 New York open, and a six bar session makes the score coarse. Above 1h the script draws nothing on purpose.
On 15m I read the dashboard first: which session is live, how its range compares with average, and what the pair stats say about the current regime. Levels graded A or S from a session that expanded on volume are the ones I treat as real liquidity references, especially with key confluence. Then I watch how the next session treats them. A sweep, thick border, stops taken and price rejected, is a different trade than a clean run. I drop to 5m for execution around those levels and during killzones. I do not use this above 1h, and the script will tell you the same.
The way I think about it: session highs and lows are liquidity pools with a clock attached. Equal highs can form anywhere, but a session extreme tells you which desk made the level, when it stops being defended, and, through the statistics, what usually happens to it next.
SETTINGS THAT MATTER
- Sessions: four windows, each with its own IANA timezone (Asia/Tokyo, Europe/London, America/New_York by default). These are real timezone names, not UTC offsets, so daylight saving is handled automatically. The sessions simply follow their local clocks.
- Weekdays Only: off by default. Crypto trades the weekend, and weekend sessions usually grade D by themselves on thin range and volume. Turn this on and everything restricts to Monday through Friday: the weekend becomes one long Dead Zone, Friday New York levels wait for Monday Asia, and the countdown switches to a days format.
- Max Session Boxes: 42 keeps two weeks of session history for a zoomed-out view, 6 keeps two days for intraday focus.
- Run Levels Become: greyed history or deleted. Your choice of how loud the past is.
- Focus Fade: levels more than 6 ATR away from price render dimmed, gold glow included, so your eye goes to what is in play.
- Killzones: four windows in New York time, each with its own color. London Close is off by default. Killzone Range Lines adds the frozen high and low of each completed killzone as dashed lines.
- Timeframe guard: above 60 minutes the script draws nothing and says why. This is an intraday tool, and pretending otherwise would only produce misleading levels.
ALERTS
Session Opened, Session Closed, New A/S Session Level, Session Level Swept, Session Level Run, Killzone Started, Session Midline Tapped, Sweep Rate Threshold (a pair crossing 70 percent swept with n of at least 10).
CALCULATION DETAILS
- All state changes happen on confirmed bars. Sweeps, runs and statistics never repaint within a bar.
- Sessions use Pine session strings with full IANA timezone support. Without a day filter, Pine fires sessions on all seven days. That is correct for 24/7 markets, and it is what the Weekdays Only toggle changes.
- The rolling averages for range and volume use the last 20 completed sessions of the same type, calculated before the current session is added. A session is never compared with itself.
- A sweep needs a wick beyond the level with the close back inside the 0.1 ATR buffer. A run needs a close beyond the level plus the buffer. A first sweep marks the level, a later run still resolves it.
- Outcomes are only recorded while the judging session is open. A level that survives its judge counts as held at the judge's close.
- The statistics are computed from the bars your chart loads. They reload per chart timeframe. 15m loads the most history and gives the highest n. On 5m the same engine runs on roughly a third of the sample, treat those percentages as indicative.
HONEST LIMITATIONS
- The statistics describe the past, they do not predict. They tell you what this chart did over the loaded history, not what it will do next.
- n differs per pair by design. Levels run inside the Dead Zone leave the population before their judging session opens, which is why the New York pairs carry a smaller n. That is honest counting, not a bug.
- Statistics depend on the chart timeframe and the loaded history, so two timeframes show different percentages. Neither is wrong, they measure different samples.
- With Weekdays Only off, weekend sessions are part of the statistics. With it on, both n and the percentages change, because you measure a different market. Neither setting is the truth, they answer different questions.
- Scores compare a session with its own rolling history, so the first 20 sessions of each type on a fresh chart carry less reliable scores while the averages fill up.
- On 1h charts bar alignment can cut off session opens (there is no 09:30 bar on an hourly chart). That is part of why the timeframe guard sits at 60 minutes.
ORIGINALITY
The session and killzone concepts come from the public ICT vocabulary and from years of session-based intraday trading. Every line of code, the scoring system, the sweep versus run grammar, the judged-while-open statistics engine, the Dead Zone concept and the visual language are my own work.
Questions and suggestions are welcome in the comments. If the stats surprise you on your market, that is usually the most interesting place to start reading.

Session Levels IQ [TradingIQ]Hello Traders!
🔹 Session Levels IQ
Session Levels IQ is a session-based percentage grid tool designed to map how far price typically travels away from each session open.
Instead of treating a session as a simple open-high-low-close range, this tool builds a structured level framework around the session open and tracks which distances tend to get reached, how often they get reached, and what price typically does after touching them .
Think of it as a way to study session expansion behavior around the open .
This indicator records historical observations to show what typically happens.
It’s not a strict probability model, but more of a history book of past behavior.
session-based percentage levels built outward from the open
custom session or timeframe-based session construction
hit-rate tracking for each distance level
typical move-after-hit measurement
normal vs unusual level zoning
optional coloring by historical hit rate or move-after-hit
reference price line for inspecting post-hit behavior
🔹 What the tool shows
🔸 Session-centered level grid
Each session begins from its opening price, and the script builds levels outward in configurable percentage intervals.
This creates a structured grid above and below the session open, helping you visualize how price expands relative to where the session started.
This helps reveal:
how far price tends to travel from the session open
which percentage distances are reached most often
how session expansion behaves over time
🔸 Historical hit rate by level
The script tracks whether each percentage level gets touched across completed sessions.
Over time, this produces a running statistical view of how often price reaches specific distances from the open.
This allows you to observe:
which distances are commonly reached
which distances are less typical
where session expansion begins to become unusual
🔸 Typical move after hit
In addition to tracking whether a level is reached, the script also records what price typically does after touching that level.
For levels that get hit, it measures the median follow-through after contact.
This helps show:
whether certain levels tend to lead to larger continuation
whether some levels produce relatively small follow-through
how post-hit behavior differs across the grid
This is not just about whether price gets somewhere.
It is also about what tends to happen once it gets there .
🔸 Normal vs unusual zones
A configurable normal range defines which distances from the open are considered relatively typical and which fall outside that range.
Levels inside this zone are treated as normal, while levels beyond it are treated as more unusual.
This helps identify:
common session movement areas
stretched or less typical expansion zones
where price is trading beyond its more ordinary session behavior
🔸 Level coloring modes
The script can visually color levels in different ways depending on what you want to study.
Available modes include:
By Hit Chance
By Move After
None
With hit-chance coloring, levels are shaded based on how frequently they are reached.
With move-after coloring, levels are shaded based on the magnitude of the typical move after price touches them.
This makes it easier to spot:
frequently reached levels
less common extension areas
levels associated with larger follow-through
🔸 Custom session support
You can build the framework using either:
a standard session timeframe such as 1D
a fully custom intraday session window
This makes the tool flexible for traders who want to study:
daily opens
custom market sessions
specific trading windows
🔸 Whole-number level emphasis
The script can optionally emphasize whole-number percentage distances so that major percentage thresholds stand out more clearly on the chart.
This can help when you want to quickly distinguish:
major percentage levels
minor intermediate levels
cleaner structural reference points
🔸 Reference price line
An optional draggable reference line lets you place a price directly onto a level and inspect the typical move after that level is hit.
This gives you a visual way to explore:
how levels behave after being reached
which zones tend to continue further
which levels show more limited follow-through
This feature is best viewed as exploratory context , not as a standalone signal.
🔸 Session range box
The script can also draw a box around the current session’s working range, helping frame the active expansion area as the session develops.
This gives additional context for:
the current session’s high-to-low development
where the grid sits relative to the active range
how much of the session’s expansion has already formed
🔹 How to read it
Each component provides a different layer of session information:
Session open → anchor point for the grid
Percentage levels → structured expansion distances from the open
Hit chance → how often a level gets reached across sessions
Move after hit → typical follow-through once a level is touched
Normal range → common vs unusual expansion territory
Reference line → exploratory view of post-hit behavior
🔹 Why this tool is useful
It gives you:
a structured way to study session expansion around the open
historical context for which distances are commonly reached
visibility into which extensions are relatively unusual
insight into what price typically does after contacting a level
a contextual framework for session movement analysis
🔹 Best use cases
studying how far sessions typically expand from the open
identifying common vs stretched extension zones
comparing likely and unlikely distance levels
adding structure to open-based session analysis
exploring how price tends to behave after touching key percentage levels
🔹 Important note
This tool is based on historical session behavior and percentage-distance tracking.
That means:
it is descriptive, not predictive certainty
results depend on the instrument and timeframe being analyzed
smaller level spacing creates more detail, but also more density
typical move-after-hit is informational and should not be treated too literally
🔹 Inputs you can customize
The script includes flexible controls such as:
custom session toggle
custom session time
session timeframe
level spacing percentage
normal range percentage
label detail level
label size
label side
show all stored levels
whole-number level emphasis
session range box display
level coloring mode
reference price line
Closing Notes
Session Levels IQ is built to shift the focus from simply asking where price is now to asking how far price has historically tended to travel from a session open, how often those levels are reached, and what usually happens after contact .
It helps turn session expansion into a more structured and measurable framework , so you can view open-based movement with more context than raw candles alone.

Killzones & Key LevelsThe ICT Killzones + Key Levels indicator is a comprehensive technical analysis tool that consolidates institutional trading logic and ICT (Inner Circle Trader) concepts into a single interface. Its primary distinction lies in optimizing all calculations based on actual market opening times—specifically the New York 18:00 session rollover—rather than the standard midnight (00:00) reset.
It visually represents critical Killzone regions, such as Asia, London, New York AM/PM, and New York Lunch, using dynamic boxes on the chart. These zones highlight periods of peak volatility and liquidity, clarifying areas where price is most likely to react. Additionally, it calculates session-based Daily, Weekly, and Monthly (DWM) open levels to align with institutional data, making intraday bias much easier to determine.
The indicator provides a True Day Open (TDO => NYMO) level as a vital reference point throughout the day while automatically tracking Previous Day, Week, and Month Highs and Lows (H/L). By drawing vertical day-divider lines at 18:00, it allows traders to see the "true" trading day. This enables Futures and Forex traders to analyze market cycles based on institutional liquidity flow rather than just calendar hours.
Finally, it includes a volatility analysis table that displays the current price range for each session. With a fully customizable structure, you can adjust sessions, colors, and timeframes to fit your specific strategy. In essence, this tool serves as a professional roadmap for Smart Money Concepts (SMC) traders who prioritize session structure over traditional timekeeping. Indicator
[ A L P H A X ] Session Levels MapAlphaX Session Levels Map — Session Boxes, H/L Extensions, PDH/PDL, PWH/PWL, EQ Midpoints & Live Level Status Table
AlphaX Session Levels Map is a comprehensive session structure and key level visualization tool built for traders who use institutional time-based analysis. It maps the three major trading sessions — Asia, London, and New York — alongside Previous Day and Previous Week high, low, open, and close levels, all on a single clean overlay with a live reference table showing every level's current price and status in real time.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
🕐 Session Mapping
Each session — Asia, London, and New York — is tracked independently from its configurable GMT start time to its end time. As price moves through the session, the indicator builds the session range in real time, recording the highest high and lowest low reached.
When the session closes, the indicator draws:
A session box spanning the full session range from open bar to close bar, clearly marking the price area the session occupied
A session name label centered inside the box at the session high
An EQ midpoint line at the exact equilibrium between the session high and low — the 50% level of the range, a key reference for ICT and SMC traders
Extended H/L lines that project forward from the session close and remain active until price breaks through them — at which point the line terminates exactly at the breakout bar
All session drawings are controlled by a Sessions to Show setting — older sessions beyond your chosen limit are automatically removed, keeping the chart clean regardless of how far back you scroll.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📐 Key Levels
Previous Day High / Low (PDH / PDL)
Plotted at the start of each new trading day using the prior day's confirmed high and low. Lines extend forward across the current day and labels follow price to the right edge of the chart at all times.
Previous Day Open / Close
The prior day's open and close prices plotted as separate lines — useful for identifying whether the current day is trading above or below the previous day's range midpoint and for gauging bullish or bearish displacement.
Previous Day Midpoint (PD Mid)
The exact 50% equilibrium of the previous day's high-to-low range. A key reference level for mean reversion setups and judging whether price is premium or discount relative to the prior day.
Previous Week High / Low (PWH / PWL)
Plotted at the start of each new week using the prior week's confirmed high and low. Drawn one width heavier than daily levels to visually distinguish their higher timeframe significance.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📋 Live Level Status Table
A compact reference table updates on every bar and shows every active level at a glance:
Level — the name of the level, color-coded to match its line on the chart
Price — the exact price of the level formatted to the instrument's tick size
Status — whether price is currently Above ▲ or Below ▼ the level, color-coded green and red in real time
The table covers all active levels: PDH, PDL, PD Open, PD Close, PD Mid, PWH, PWL, Asia H/L, London H/L, and NY H/L. Levels that are disabled in settings are automatically hidden from the table — no blank rows or clutter.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━

🚀 How to Use
Add AlphaX Session Levels Map to your chart on any intraday timeframe — M1 through H1 works best
Check the live table immediately — it shows you at a glance whether price is above or below every key level without needing to scan the chart
Use PDH and PDL as the first reference for the day — a clean break and hold above PDH is bullish displacement; a rejection at PDH is a premium reversal zone
Use PWH and PWL for higher timeframe context — these are the weekly liquidity pools that institutional flow targets
Watch Asia High and Low during London open — London frequently raids one side of the Asia range before committing to direction
Use session EQ midpoints for mean reversion entries — price returning to a session's 50% level after displacement is a high-probability setup in ICT methodology
Enable session background highlighting during live trading to instantly identify which session is currently active
Set PDH/PDL and PWH/PWL break alerts with your webhook URL for real-time notifications when key levels are breached
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
👥 Who This Is For
🥇 Gold (XAUUSD) traders — session levels are among the most reliable reference points for XAUUSD intraday structure
📉 Forex traders — Asia, London, and NY session highs and lows are foundational to smart money and ICT-based analysis on all major pairs
📊 Index traders — session structure is equally applicable to US30, NAS100, SPX500, and DAX

📈 Multi-session traders — the live status table makes it easy to track where price sits relative to all timeframes simultaneously
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
📝 Notes
All session times are based on GMT/UTC — adjust start and end hours to match your broker's GMT offset if needed
Designed for intraday timeframes — M1 to H1. On daily or weekly charts session boxes will not render meaningfully
Previous Day and Week levels use confirmed closed bars via request.security — no repainting
Extended H/L lines terminate at the exact bar where price breaks them — the break is detected on bar close for high timeframes and intrabar for lower timeframes depending on chart resolution
Sessions to Show controls drawings for boxes, labels, and midpoints — extended H/L lines always show only the most recent session's projection

SMC: Multi-TF Bias & HTF BOS with SessionsOverview
The HTF BOS (Session) - Precision Lines is a comprehensive trading tool designed for Smart Money Concepts (SMC) and price action traders. It identifies Higher Timeframe (HTF) Break of Structure (BOS) levels while filtering them based on specific trading sessions. Additionally, it features a built-in Bias Dashboard that tracks trend alignment across three different timeframes to help you stay on the right side of the market.
Key Features
1. Precision HTF BOS Tracking
Unlike standard indicators that only mark the breakout candle, this script uses high-precision pivot detection to identify the exact origin of a structural high or low.
Tam Yapışık Çizgiler (Precise Lines): The BOS lines are drawn exactly from the pivot point to the breakout point, providing a clean and professional look on your chart.
HTF Integration: You can track structure from a higher timeframe (e.g., 4H) while trading on a lower timeframe (e.g., 15m or 5m).
2. Session Filtering (Time Sensitivity)
Structural breaks are most reliable when they happen during high-volume periods.
The script includes a Session Filter (London & New York).
If enabled, the indicator will only plot BOS levels that occur during your specified trading hours, helping you avoid "fake-outs" or noise during low-liquidity periods (Asian session/After-hours).
3. Multi-Timeframe Bias Dashboard
Stay aware of the "Big Picture" without constantly switching charts. The dashboard monitors three custom timeframes (e.g., Daily, 4H, 1H) and determines if the structure is Bullish or Bearish.
Strong Buy/Sell Signals: When all three timeframes align, the status cell highlights as "BUY" or "SELL."
Wait Status: If timeframes are in conflict, the dashboard suggests "WAIT," encouraging disciplined trading.
How to Use
Define Your Bias: Set your three Bias Timeframes in the settings to match your higher-level strategy.
Set Your BOS TF: Choose the timeframe you want structural breaks to be calculated from (usually one or two steps above your entry chart).
Adjust Sensitivity: Use the "Pivot Sensitivity" setting to filter between minor and major structural points.
Confirm with Session: Enable the session filter to ensure you are only trading breaks that occur during the NY or London sessions.
Settings
Bias Dashboard Settings: Customize the TFs and pivot sensitivity for trend analysis.
BOS & Session Settings: Set your target HTF for drawings and define your trading window (NY Timezone supported).
Visual Settings: Full control over colors (Bullish/Bearish), table positioning, and text sizes. Indicator

Session Bar Color (US Time)This script is designed to change the color of bars on a trading chart based on different trading sessions in Eastern Time (ET). It is different from currently published scripts in that it specifically focuses on US time sessions and provides a customizable approach to defining and coloring each session.
To use this script, you can apply it to a chart by selecting it from the list of available indicators or overlays.
The script is meant for traders who are interested in visualizing different trading sessions on their charts. By coloring the bars based on session boundaries, it can help traders quickly identify session changes and potentially adjust their trading strategies accordingly. Mostly it's used to draw the high and low zones of each session.
The markets this script is suitable for are those that operate within the US time zones, as it specifically focuses on Eastern Time (ET) sessions. It can be used for various types of markets, including stocks, futures, and forex.
The conditions for each session are defined using the input. session function, which allows you to specify the start and end times for each session. The script includes four sessions: Asian, London, USA, and New York. By modifying the defval parameter for each session input, you can customize the session times to fit your specific trading preferences or time zone.
The script uses the time function to check if the current bar falls within a particular session. If the condition is met, it sets the color of the bar using the bar color function. Each session is assigned a different color: black for the Asian session, teal for the London session, a custom RGB color (dark red) for the USA session, and red for the New York session.
It's important to note that this script assumes the time zone of the trading platform is set to "Etc/GMT+4" to align with Eastern Time (ET). If your platform uses a different time zone, you may need to adjust the time function calls to match your desired time zone. Indicator
