🧲 LIQUIDITY GRAB DETECTOR [AGPro Series]
Detects single-bar multi-level liquidity raids — the precise moment price sweeps a cluster of 2 or more distinct liquidity pools within a single candle and immediately reverses. Built for ICT, Smart Money, and institutional order-flow analysis, this engine identifies the liquidity raids that matter most: simultaneous multi-level stop hunts that typically precede the sharpest reversals.
═══════════════════════════════════════
🔹 OVERVIEW
Most liquidity tools either track single sweeps or lifecycle-based breach-and-reclaim patterns. This detector focuses on a different, rarer, and higher-conviction event: the single-bar multi-level raid. When one candle sweeps a cluster of two or more untouched liquidity levels (swing highs/lows, session H/L, previous day H/L, previous week H/L) in a single motion, the odds of a meaningful reversal increase significantly. The engine validates each grab with four independent filters, deduplicates overlapping levels, merges adjacent reversal zones for a clean chart, tiers signals by quality, and projects forward target zones.
One-click preset modes (Aggressive / Balanced / Conservative / Custom) make the detector instantly suitable for any style — from high-frequency scalping to premium-only confluence trading — without manual tuning.
This is not a strategy and makes no directional prediction. It is a detection and visualization engine for a specific institutional order-flow footprint.
═══════════════════════════════════════
🔹 UNIQUE EDGE — HOW THIS DIFFERS
The single-bar multi-level criterion is the defining separator from conventional liquidity tools:
▪ Traditional liquidity sweep detectors flag any single-level sweep. High signal rate, low conviction per signal.
▪ Breach-and-reclaim engines (equal-highs / equal-lows style) require a full lifecycle across multiple bars. Different mechanic, different timing.
▪ This detector requires a cluster of 2+ distinct liquidity levels to be swept in a single candle, within a user-defined ATR proximity. ATR-normalized thresholds adapt across all timeframes and symbols.
▪ ATR-based level deduplication merges coincident sources (e.g. Swing + PDH stacked at the same price) into a single logical level, preventing inflated sweep counts.
▪ Zone overlap-awareness: adjacent same-direction reversal zones are merged into a single extended zone rather than piling multiple boxes on top of each other. Premium, chart-clean visualization.
▪ Strikethrough length clamp keeps historical consumed-level lines from crossing the entire chart, even on long-running indicators.
▪ Preset modes encapsulate calibrated filter stacks, making the detector genuinely plug-and-play.
The combined filter stack (cluster + volume + wick + reversal + cooldown + dedup + zone-merging) produces fewer but significantly higher-quality signals with a clean visual footprint.
═══════════════════════════════════════
🔹 METHODOLOGY
Preset modes calibrate the detection engine with one selection:
▪ Aggressive — minimum 2 levels, 0.7 ATR cluster, 1.1× volume, 0.15 ATR wick, 2 bar cooldown.
▪ Balanced — minimum 2 levels, 0.45 ATR cluster, 1.5× volume, 0.3 ATR wick, 5 bar cooldown. Default.
▪ Conservative — minimum 3 levels, 0.35 ATR cluster, 2.0× volume, 0.45 ATR wick, 10 bar cooldown. Premium-only.
▪ Custom — honors manually configured input values.
Level registry with deduplication. The script maintains a live registry of untouched liquidity levels built from four configurable sources. Incoming levels within a configurable ATR tolerance of an existing level are merged. Each level is time-stamped, capped at a configurable maximum count, and pruned once it ages beyond the lookback window or is consumed by a grab.
Cluster detection. On every bar, the engine scans active levels on both sides and classifies a bar as a multi-level sweep candidate when it penetrates the minimum level count whose vertical span fits within the ATR proximity band.
Confirmation layers:
1. Volume spike — grab bar volume must exceed the rolling SMA by the preset multiplier.
2. Wick ratio — rejection wick on the grab side must exceed the preset ATR fraction.
3. Immediate reversal — within a configurable window, price must close back beyond the swept cluster.
4. Cooldown — after a confirmed grab, new detections are suppressed.
Zone overlap-awareness. When a new grab's reversal zone falls within a configurable ATR distance of a recent same-direction zone, the existing zone is extended rather than drawing a new overlapping box. Aggregate targets stay clean.
Quality tier classification. Confirmed grabs are automatically tiered by level count, with 4-level grabs and 5+ level grabs receiving progressively stronger visual emphasis.
═══════════════════════════════════════
🔹 SIGNALS & VISUALS
Confirmed bullish grab — triangle marker below the bar, "LIQ GRAB · N levels swept" label with tier stars for high-quality grabs, and a forward-projected reversal zone above the cluster with a target micro-label.
Confirmed bearish grab — mirror image with bear coloring.
Stagger-aware label placement. When multiple confirmed grabs occur close together on the chart, their labels are automatically offset vertically to prevent visual overlap.
Clean default visual profile. Swept-level strikethrough lines are disabled by default for a premium chart-clean look; enable them for detailed post-grab review. When enabled, a max-age clamp prevents extremely long lines.
Statistics panel (8 rows) — active level count, total grabs, bars since last grab, last grab source composition (dynamic, e.g. "PDL+Swing"), bullish vs bearish breakdown, reversal success rate, and average levels swept per grab.
Alerts — separate alert conditions for bullish and bearish grab confirmations, triggered on bar close.
═══════════════════════════════════════
🔹 KEY INPUTS
Detection Engine
▪ Preset Mode — Aggressive / Balanced / Conservative / Custom.
▪ Minimum Levels Swept, Cluster Proximity, Cooldown — honored in Custom mode.
▪ Level Deduplication (ATR) — merge tolerance for coincident levels.
▪ Level Lookback, Max Active Levels — registry housekeeping.
Liquidity Level Sources — swing highs/lows, session H/L, PDH/PDL, PWH/PWL.
Confirmation Filters — volume multiplier and averaging length, reversal window, minimum wick ratio, ATR length.
Visuals
▪ Toggle labels, strikethroughs, zones, statistics panel.
▪ Label and panel font size (default Normal).
▪ Panel position (8 options) and theme (Dark / Light).
▪ Zone projection length, zone height, zone transparency.
▪ Zone merge distance (ATR-based overlap suppression).
▪ Max strikethrough length (bars).
═══════════════════════════════════════
🔹 HOW TO USE
1. Start with Balanced preset on any timeframe. The ATR-based cluster logic adapts automatically, but 15m–4H timeframes on liquid instruments produce the cleanest signal set.
2. Switch to Conservative for premium-only signals at key institutional levels, or Aggressive when scalping intraday liquidity dynamics.
3. Watch for grab labels near well-defined liquidity clusters — session opens, PDH/PDL interactions, and at range edges. Tiered grabs (4+ levels raided in one bar) deserve special attention.
4. Use the reversal projection zone as a reference target area, not a mechanical take-profit. Combine with your existing structure, order blocks, or mean-reversion levels.
5. Check the "Last Sources" panel row to see which specific liquidity pools were raided most recently.
6. For detailed post-grab analysis, enable "Show Swept Level Strikethroughs" in the Visuals group. For a clean chart, leave disabled.
7. For fine-grained control, select Custom mode and adjust each filter manually.
═══════════════════════════════════════
🔹 LIMITATIONS & TRANSPARENCY
▪ No repaint on confirmed signals — grabs are finalized only after the reversal window closes with all filters passing. Swing pivots used as level sources are inherently delayed by the pivot length (standard pivot behavior).
▪ The reversal success metric uses a fixed 1 ATR / 10 bar definition and is provided as context only. It is not a performance claim or win rate.
▪ In strongly trending markets, multi-level sweeps can occur without reversal, producing failed grabs. The filter stack reduces but does not eliminate this.
▪ On very low-liquidity symbols or extremely short timeframes, volume data can be noisy. Consider disabling the volume filter in those conditions.
▪ Session, PDH/PDL, and PWH/PWL levels are derived from the chart symbol's native session definition.

🔧 UPDATE NOTES - V1.5This update focuses on visual hierarchy, educational structure, and publication-readiness.
The core purpose of the script remains unchanged.
This release improves how liquidity grabs, reaction targets, and post-sweep context are presented on the chart.
This script continues to function as an analytical and visualization tool.
It does not attempt to predict price direction or provide guaranteed outcomes.
------------------------
What Changed
------------------------
• Added centered target-zone badges
Projection zones now use separate centered labels such as BULLISH TARGET ZONE and BEARISH TARGET ZONE.
These badges are separate label objects and do not rely on box text.
• Added grab-to-target path rails
Confirmed liquidity grabs can now draw a bold educational path from the sweep context toward the projected target zone.
This helps the chart explain the sweep-to-reaction idea visually.
• Preserved full grab-label wording
The existing descriptive labels such as LIQ GRAB · 2 levels swept are intentionally preserved in this version.
• Improved default visual cleanliness
Tiny triangle markers are now optional and disabled by default because the main label and path already identify the event.
• Refined panel flow
The panel now emphasizes Last Grab, Grab Side, Sources, Bias, Reversal Rate, Avg Levels, and Active Levels.
------------------------
Visual Improvements
------------------------
• Replaced tiny target text with contrast-safe centered target badges
• Added clearer zone borders and stronger chart hierarchy
• Added optional educational path rails for first-glance interpretation
• Reduced duplicate event marking by making triangle markers optional
• Preserved descriptive grab labels to maintain educational clarity
------------------------
Interface & Usability
------------------------
• Added Show Centered Target Badges control
• Added Show Grab-to-Target Path control
• Added Grab Path Width control
• Added Show Triangle Markers control
• Added Maximum Visual Sets control for cleaner historical chart review
• Expanded panel themes to Elite Dark, Slate, and Clean Light
------------------------
Behavior Notes
------------------------
This update does not change the core analytical logic of the script.
The level registry, multi-level sweep detection, volume filter, wick filter, reversal confirmation, cooldown, statistics, and alert logic remain aligned with the prior version.
Users should interpret outputs the same way as before, but with a more educational visual structure.
------------------------
Limitations Reminder
------------------------
The script remains a rule-based analytical tool.
Market conditions such as volatility, liquidity, timeframe differences, and session behavior may affect how liquidity grabs appear.
Outputs should always be interpreted within broader market context.
------------------------
Risk Reminder
------------------------
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.

UPDATE NOTES - v1.6This update focuses on readability and label placement.
The core purpose of the script remains unchanged. This release refines how the
existing liquidity-grab detection and target zones are presented on the chart.
This script continues to function as an analytical and visualization tool. It
does not attempt to predict price direction or provide guaranteed outcomes.
------------------------
What Changed
------------------------
- Target-zone badges moved off the candles
The centered "TARGET ZONE" badge now sits in the forward-projected section of
each target zone instead of over the historical candles. It stays vertically
centered in the zone while remaining clear of price action, so the zone label
is readable at a glance.
- Cleaner label wording
Separators inside the grab labels, source readout, and alerts were simplified
for consistent, universal rendering across platforms.
------------------------
Visual Improvements
------------------------
- Improved readability by keeping target-zone badges out of the candles.
- Reduced overlap between grab labels and target-zone badges near the right edge.
- Refined visual hierarchy so the grab labels, target zones, and grab-to-target
paths each read clearly.
- Preserved label offsets and staggering that keep grab labels above or below
candles.
------------------------
Interface & Usability
------------------------
- Optimized target-zone badge placement for a cleaner layout.
- Improved label readability in busy market segments.
- Adjusted default visual presentation for a more balanced, premium appearance.
- Enhanced overall user experience without changing core logic.
------------------------
Behavior Notes
------------------------
This update does not change the core analytical logic of the script.
The goal is to improve clarity and usability, not to introduce new predictive
behavior. The liquidity-level registry, the multi-level grab detection, the
confirmation filters, the reversal confirmation, the target zones, and the
statistics panel all behave exactly as before.
Users should interpret outputs the same way as before, but with a cleaner
layout.
------------------------
Limitations Reminder
------------------------
The script remains a rule-based analytical tool.
Market conditions such as volatility, liquidity, and timeframe differences may
affect how grabs, levels, and target zones appear. Outputs should always be
interpreted within broader market context.
------------------------
Risk Reminder

🔧 UPDATE NOTES - 1.7This update turns the Liquidity Grab Detector into a decision-focused tool that
scores each raid and tells you what to do after it. The core detection logic
(multi-level sweep + volume + wick + reversal) remains unchanged. This script
continues to function as an analytical and visualization tool. It does not
predict price direction or guarantee outcomes.
------------------------
What Changed
------------------------
- Next-Action Readout
A new Action row tracks the live setup after each grab (Long Setup, Short Setup,
Target In Play, Target Reached, Scan Liquidity).
- Grab Quality Score
Every confirmed grab is now scored 0-100 from the number of levels swept and the
quality of the liquidity sources involved.
- Hardened Reversal Rate Proof
Statistics are now confirmed-bar gated and non-repainting, with a configurable
success window and same-bar exclusion, and the sample size is shown alongside the
rate.
- Cleaner Labels
Removed the asterisk tier markers from grab labels; grab strength is now expressed
through the panel Quality score instead.
------------------------
Visual Improvements
------------------------
- Reorganized the panel into a decision-first layout led by Action and Quality
- Refined grab label text color for a cleaner, more consistent look
- Reduced label clutter by moving tier emphasis into the panel
- Kept target zones, badges and grab-to-target paths focused and readable
------------------------
Interface & Usability
------------------------
- Added a Reversal Success Window input for transparent proof tuning
- Improved first-glance interpretation through clearer information flow
- Made signals confirm on bar close for stable, non-repainting behavior
- Enhanced overall experience without changing the core detection logic
------------------------
Behavior Notes
------------------------
This update does not change how liquidity grabs are detected. The goal is clearer
interpretation and added decision context. Historical signals remain the same;
only realtime behavior is now non-repainting.
------------------------
Limitations Reminder
------------------------
The script remains a rule-based analytical tool. Volatility, liquidity and
timeframe differences can affect how grabs, zones and statistics appear. Always
interpret outputs within broader market context.
------------------------
Risk Reminder
------------------------
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.
