Judas Swing Detector [algo_aakash]Judas Swing Detector is a session-based reversal indicator that models the institutional Judas Swing as a complete, sequential price event rather than a single false-breakout candle. Instead of flagging every session-open wick that reverses, the script requires a full chain of confirmed conditions — a locked Initial Range, a liquidity sweep beyond it, a rejection close back inside, an optional market structure shift, institutional-grade displacement, and higher-timeframe trend agreement — before a signal is ever scored, drawn, or alerted.
Problem Statement
A Judas Swing is commonly described as "price sweeps one side of the session open and reverses," but that description alone matches an enormous number of ordinary, low-quality wicks. Scripts that flag every such wick generate far more noise than usable signal, because a sweep and a close-back-inside is only the first half of the institutional sequence — it says nothing about whether the reversal has real structural or momentum support, or whether it agrees with the underlying daily trend.
This indicator addresses that gap by treating the Judas Swing as a seven-stage sequence and only surfacing a signal once every enabled stage has been satisfied on confirmed price data, with the overall setup then ranked by a disclosed, weighted confidence score.
Methodology
A session window (London Open, New York Open, or a fully custom session and timezone) drives an Initial Range engine that locks the session's high and low once a configurable opening window (5, 10, 15 or 30 minutes) elapses. The Initial Range is drawn as a transparent box and extends for the remainder of the session.
Once the Initial Range is locked, the script watches for a liquidity sweep: a wick that pierces beyond the Initial Range high or low by at least a minimum ATR-based distance, with the same candle closing back inside the range. This closing-back-inside requirement is what separates a genuine sweep-and-reject from an ordinary breakout continuation.
A confirmed sweep becomes a pending candidate. If Market Structure Confirmation is enabled, the candidate must be followed by a genuine structure shift measured against minor swing pivots that form strictly after the sweep bar: a higher high following a low-side sweep, or a lower low following a high-side sweep. Candidates that do not produce this structure shift within a configurable bar timeout are discarded with no signal created.
A qualifying candidate is then subjected to a Displacement Filter, requiring the confirming candle's body to reach a minimum ATR multiple, and an optional Higher Timeframe Bias check, requiring a fast/slow EMA relationship on a user-selected higher timeframe (e.g. 1H, 4H, Daily) to agree with the reversal direction. Only after every enabled stage passes does the script compute the Judas Confidence Filter score.
The Judas Confidence Filter combines five independently disclosed, user-weighted factors into a single 0-100 score: sweep depth (how far price pierced beyond the Initial Range in ATR units), displacement (the confirming candle's body size in ATR units), HTF agreement (the normalized separation between the fast and slow higher-timeframe EMA, reflecting how decisively the higher-timeframe trend supports the direction), rejection quality (where the sweep candle closed within its own range), and reversal aggression (how few bars elapsed between the sweep and structure confirmation). Weights are user-adjustable and auto-normalized. A signal is only plotted and only triggers alerts if its score meets the Minimum Confidence Score threshold — this is a genuine filtering mechanism that changes what is drawn, not a cosmetic label applied afterward.
Confirmed signals optionally draw an Entry Zone between the 50% and 62% retracement of the confirming displacement candle, reflecting where institutional-style retracement entries are commonly sought after a confirmed reversal, along with a stop-reference line at the sweep extreme. Both extend forward and are visually dimmed once price closes back through the sweep extreme, marking the setup invalidated.
Signal Workflow
Step 1 — the selected session opens and the Initial Range begins building from the session's first 5-30 minutes of price action.
Step 2 — the Initial Range locks; the script now watches for a liquidity sweep beyond either side of that locked range.
Step 3 — a wick pierces beyond the range by a minimum ATR distance and the same candle closes back inside, registering a pending sweep candidate.
Step 4 — if enabled, the candidate must be followed by a market structure shift measured against post-sweep swing pivots, within a bounded bar timeout.
Step 5 — the confirming candle must clear the ATR-based displacement threshold, and if enabled, the higher-timeframe EMA bias must agree with the reversal direction.
Step 6 — the completed sequence is scored by the Judas Confidence Filter across five weighted factors; only scores at or above the minimum threshold are plotted and alerted.
Step 7 — an optional 50%-62% entry zone and stop-reference line are drawn from the confirming candle and remain active until price closes back through the original sweep extreme.
Why This Indicator Is Different
Most public "Judas Swing" or session-sweep scripts fire on the sweep-and-close-back-inside event alone, with no structural or momentum confirmation and no higher-timeframe context.
This script models the full institutional sequence explicitly — session, Initial Range, sweep, rejection, structure shift, displacement, HTF agreement — and only creates a signal after every enabled stage resolves in order on confirmed bar closes.
The Judas Confidence Filter converts five independently disclosed factors, including reversal aggression measured in bars-to-confirmation and rejection quality measured from close position within the sweep candle's own range, into a single adjustable score rather than a binary flag.
Confidence weighting is fully exposed, letting the ranking be tuned toward sweep depth, displacement strength, higher-timeframe agreement, rejection quality, or reversal speed depending on the trader's approach.
The optional 50%-62% Entry Zone models a specific, disclosed institutional retracement convention rather than simply marking the signal bar.

Practical Usage
Use the status panel's HTF Bias reading as directional context before evaluating an individual Judas signal.
Treat a High-Confidence (Elite) signal as a materially stronger setup than one that merely clears the minimum threshold, since it reflects agreement across all five scored factors rather than a narrow pass.
Raise the Minimum Confidence Score on lower timeframes or noisy instruments to reduce the number of marginal signals generated.
Disable Require MSS Confirmation only if you specifically want to evaluate the sweep-and-rejection event on its own, understanding this removes one of the seven confirming stages.
Combine the alert feed with a broader trade plan, since each alert marks a structural event, not an execution signal.
Limitations
The Initial Range and session logic depend on the chart's intrabar data matching the selected session window; behavior on markets with irregular or 24-hour sessions may differ from traditional FX/futures sessions.
Market structure confirmation depends on minor swing pivots, which require bars to form on both sides before they confirm, introducing an inherent, bounded delay.
Confidence scoring is a relative, disclosed ranking and does not predict the outcome of any individual signal.
The higher-timeframe bias is read via a standard non-repainting security call and reflects EMA relationship only; it is not an independent trend-strength model.
As with any structure-based tool, results will vary across instruments, timeframes, and market regimes.
Notes
This indicator is a session and structure analysis tool intended to organize and score the Judas Swing sequence through a disclosed, multi-stage validation process.
All session state, sweep detection, structure confirmation, displacement, and scoring are evaluated on confirmed bar closes only, so no element of the script repaints once drawn.
The output is intended to support structural analysis and is not a standalone buy or sell recommendation.

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 VWAP Reaction Engine [AGPro Series]Session VWAP Reaction Engine
Session VWAP Reaction Engine builds the active intraday session VWAP as a reaction anchor and classifies confirmed price behaviour around it into three clear event types — Reclaim, Bounce, and Reject — each validated by a configurable confirmation window, a minimum prior-side bar filter, and an optional VWAP slope alignment filter. A volatility-scaled reaction corridor, compact reaction zones, a session box, and a minimal right-side bias panel turn raw session flow into a clean, publication-ready read on acceptance, rejection, and continuation.
🔷 OVERVIEW
Most session VWAP tools simply plot the line. Session VWAP Reaction Engine goes further: it reads how price behaves around the line inside a selected session window (Asia, London, New York, or Custom) and labels that behaviour using three structural event classes:
• Reclaim — a confirmed cross and acceptance on the new side of session VWAP, after price has spent a minimum number of bars on the opposite side.
• Bounce — a test of the reaction corridor edge that closes back on the prevailing side, with body-range and slope alignment quality checks feeding a Strong / Clean / Weak strength read.
• Reject — a wick into session VWAP that fails to accept on the other side, resolving as pressure against the crossing attempt.
Each confirmed event paints a compact rectangular reaction zone, a single label near the zone, and updates a right-side bias panel so the current session's story is always readable at a glance.
🟦 WHAT MAKES IT DIFFERENT
▸ Event classification, not just a line. Reclaim, Bounce, and Reject are treated as distinct structural events — each with its own confirmation path and visual signature — instead of blending into a single "crossed VWAP" signal.
▸ Corridor-based reaction detection. Bounce and Reject use a volatility-scaled ATR corridor around session VWAP rather than a single-pixel touch, which matches how VWAP is typically tested in real intraday flow.
▸ Slope-aware trend filter. Optional VWAP slope alignment biases bounce events toward the prevailing session direction and filters out counter-flow reactions that tend to fail.
▸ Reaction Strength read. Bounces are classified Strong / Clean / Weak using body-to-range ratio, close location in range, and slope alignment — turning every bounce into a quality-graded event.
▸ Active-Only and Publish Focus visual modes. The chart stays clean by surfacing only the latest session and the latest confirmed reaction, with older structure fading or removed. Ideal for decision-making and presentation.
🟣 METHODOLOGY
1) Session anchor. The selected session (Asia / London / New York / Custom) resets a cumulative PV / V VWAP on every new session bar, giving a fresh reaction reference for that window.
2) Prior-side filter. Before any Reclaim or opposite-side reaction can qualify, price must have spent a minimum configurable number of bars on one side of session VWAP. This isolates structural interactions and rejects chop.
3) Reclaim confirmation. A raw cross must be followed by N consecutive confirmed closes on the new side (default 2) before the Reclaim is validated and painted.
4) Corridor reactions. A volatility-scaled corridor (ATR × user multiplier) around session VWAP defines where Bounce and Reject qualify. Bounces require a corridor-edge test plus a close back on the prevailing side with body confirmation; Rejects require a wick into session VWAP that closes on the originating side.
5) Bias and state synthesis. Live Bias (Bullish / Bearish Acceptance or Pressure, or Neutral Rotation) is derived from close position relative to VWAP and corridor. Reaction State reflects the latest confirmed event (Bullish Acceptance, Bearish Acceptance, Bounce Support, Bounce Resistance, Reject Pressure, Reject Lift).
6) Post-session context. After the session ends, the last session VWAP and corridor stay on the chart for a configurable number of bars so recent structure remains visible without polluting older history.
🟢 SIGNALS & ALERTS
Eight alertcondition hooks are provided, all bar-close confirmable:
• Bullish Session VWAP Reclaim Confirmed
• Bearish Session VWAP Reclaim Confirmed
• Bullish Session VWAP Bounce Confirmed
• Bearish Session VWAP Bounce Confirmed
• Bullish Session VWAP Reject Confirmed
• Bearish Session VWAP Reject Confirmed
• Reaction State Shifted Bullish
• Reaction State Shifted Bearish
A "Confirmed Alerts Only" toggle restricts firing to barstate.isconfirmed so alerts will not repaint before close.

🟠 HOW TO USE
1) Apply to any intraday timeframe (1m–4h). Session VWAP requires intraday data to anchor the session reference.
2) Choose the session that best fits your market focus — New York for US equities and US-hours crypto, London for FX and European hours, Asia for Asian-session flow, or a Custom window.
3) Watch the corridor as the session develops. Bounce and Reject events inside the corridor describe how the session is defending or failing the VWAP reference.
4) Use Reclaim events as session-context shifts — combine with your own structure (HTF trend, S/R, order flow) rather than treating them as standalone entries.
5) Read the right-side Bias Panel for a compact summary: Session Status, Bias, Last Reaction, Reaction Strength, Signal Age, Reaction State, and Latest Line status.
6) For screenshots and presentation use, keep Publish Focus Mode and Active-Only Mode enabled — older sessions fade and only the latest structure remains dominant.
🟤 LIMITATIONS & TRANSPARENCY
• Intraday-only. Session VWAP is meaningful only on intraday timeframes; on daily and higher, the indicator will remain idle.
• Session VWAP resets at the start of each selected session. Reactions are evaluated within that window only.
• Confirmed events use bar-close logic. Intra-bar touches of the corridor are not counted as events until the bar closes.
• Volume-dependent. Session VWAP uses symbol volume. On symbols without meaningful volume, VWAP accuracy will be limited.
• The Reaction Corridor is a volatility-scaled visual and detection band, not a support/resistance guarantee.
⚠️ RISK DISCLOSURE
This indicator is an analytical and visualisation tool. It is not a trading strategy, does not generate buy/sell recommendations, does not predict future price direction, and does not guarantee any specific outcome. All signals, zones, and panel readings describe past and current price behaviour around session VWAP, not forecasts.
Markets carry risk of loss. Always use independent risk management, position sizing, and your own trading plan. Past behaviour of any signal does not imply future performance.
Indicator
Judas Swing Detector [AGPro Series]Judas Swing Detector
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
OVERVIEW
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
The Judas Swing is a well-known intraday pattern in ICT (Inner Circle Trader)
methodology describing how price often makes a deceptive initial move at the
London or New York session open — pulling in participants in one direction —
before reversing to reveal the session's true directional bias.
Judas Swing Detector systematically identifies, visualizes, and tracks this
pattern across every London and New York session open. It shades the trap
zone, flags the reversal bar, highlights the true-direction bias, and maintains
a rolling 20-session performance log so users can assess how consistently the
pattern resolves on their chosen symbol and timeframe.
IMPORTANT — Timeframe requirement: This indicator is designed for intraday
charts of 1 hour or lower (1m, 5m, 15m, 30m, 1h). Session windows anchor the
entire logic, and a 1-hour Judas window cannot be resolved on 4-hour or higher
charts. The panel always shows an "Optimal TF: 1m - 1h" footer, and the TF
status row turns yellow with "use <=1h" if the current chart exceeds this
range.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
UNIQUE EDGE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Unlike generic session-open or breakout indicators, Judas Swing Detector is
built around a defined four-state lifecycle (Pending → Active → Forming →
Confirmed / Failed) with ATR-normalized thresholds, so detection remains
stable across different volatility regimes and asset classes.
Three design choices make it distinct:
1. Independent two-way extremum tracking inside the Judas window — both the
maximum upward and maximum downward excursion are recorded, and the larger
of the two is declared the fake move when the window closes. This removes
ambiguity in choppy openings.
2. Separate fake-move and reversal thresholds. The initial push must exceed
a minimum ATR-scaled size to qualify, and the reversal must travel a second
ATR-scaled distance beyond the session open — filtering out shallow round
trips that would otherwise inflate the signal count.
3. Rolling 20-session statistics panel reporting success rate, average fake
distance, and directional bias, giving discretionary traders an objective
view of how the pattern is behaving on their instrument before they act on
it.
4. Support/resistance-style invalidation zone drawn at the fake-move extremum
after confirmation. This gives a clear visual anchor: if price later
re-enters this zone from the opposite side during the session, the Judas
read is considered broken. The zone is a reference, not an automatic
signal.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
METHODOLOGY
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Step 1 — Session anchoring
At the first bar of the configured London or New York window the script
records the session open price, resets the two-way extremum trackers, and
transitions to the Active state.
Step 2 — Fake-move accumulation
During the window the script tracks both the maximum high and minimum low
relative to the session open. Neither is committed as the fake move until the
window closes.
Step 3 — Window-close evaluation
When the window ends the larger excursion (up vs down) becomes the fake
direction. If its size reaches the user-defined ATR multiple it qualifies and
the script transitions to the Forming state; otherwise it resets to idle.
Step 4 — Reversal confirmation
In the Forming state the script waits for price to cross the session open in
the opposite direction of the fake move and travel at least the configured
ATR-scaled distance beyond it. When that happens the swing is Confirmed and
the true direction is drawn on the chart. If the reversal window expires
without confirmation the swing is recorded as Failed.
Step 5 — History log
Every confirmed and failed outcome is appended to a rolling 20-session log
used by the statistics panel.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
SIGNALS & ALERTS
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
On-chart visuals:
• Dashed vertical line at session start (accent color)
• "LON" or "NY" label at the session anchor bar (Balanced / Detailed only)
• Shaded fake-move box from session open to fake extremum, colored opposite
to the true direction (a bearish trap is shaded in the bear tone because
the true direction is down — and vice versa)
• Optional "Fake" distance label at the extremum (Detailed density only)
• Reversal marker "X UP" or "X DOWN" at the confirmation bar, offset
from the candles for readability
• Horizontal support/resistance-style invalidation zone around the fake
extremum, extending 40 bars to the right — a visual reference for where
the Judas read would break down if price re-enters the zone
Alert conditions (toggle individually in settings):
• Judas Swing Forming — fake move has qualified, waiting for reversal
• Judas Swing Confirmed — reversal threshold crossed, true direction known
• Judas Swing Failed — reversal window expired without confirmation

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
HOW TO USE
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
Supported timeframes: 1m, 5m, 15m, 30m, 1h. These resolve a session's early
structure cleanly while keeping enough bars inside each Judas window for the
extremum tracker to work with. Recommended default: 15m or 1h.
Not supported: 4h, 1D, 1W. On these timeframes a single bar exceeds the
session window, so nothing is detected. The panel will show a yellow "use
<=1h" hint if you accidentally switch to one of these.
Recommended instruments: FX majors (EURUSD, GBPUSD, USDJPY), index futures
(NQ, ES), liquid crypto (BTC, ETH). The ATR-normalized thresholds keep the
logic portable across these asset classes.
Workflow suggestion:
1. Apply the indicator and let it observe several sessions so the panel
populates a meaningful sample.
2. Review the 20-session success rate on your specific symbol and timeframe.
This is not a forecast — it is a descriptive statistic of how the pattern
has resolved in recent history on that chart.
3. Use the Forming alert as a heads-up, and the Confirmed alert as the main
event. The true-direction arrow marks the bias of the remaining session,
not a trade entry or exit.
4. Combine with your own structural context — higher timeframe bias, key
levels, liquidity pools — before acting on any signal.
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
LIMITATIONS & TRANSPARENCY
━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━
• Not a strategy. This is a discretionary analysis tool; it neither places
orders nor implies any specific trade setup.
• Intraday timeframes only. The logic requires 1h or lower charts to resolve
the session windows. On 4h, 1D or higher the indicator will not detect
anything and the panel will show a "use <=1h" notice.
• No forecasting. Displayed statistics describe past behavior on the current
chart only and do not imply future performance.
• Pattern-dependent. When price opens and trends cleanly in one direction
without a fake move, the pattern legitimately will not trigger. Low
signal count on such sessions is expected behavior, not a malfunction.
• Session boundary sensitivity. Results depend on the configured session
windows and timezone. Outside the major FX and equities session hours the
ICT framing may not translate cleanly.
• Extreme-volatility sessions. During very large gaps or news spikes the ATR
thresholds can be dominated by a single bar; users should review the
defaults in those conditions.
• Symbol coverage. Pip conversion handles forex and JPY pairs explicitly and
falls back to tick-based sizing for other asset types. Values are intended

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.
