Strat Structure Engine + Trapped Traders

Strat Structure Engine + Trapped Traders – Detailed Description
This script identifies high-probability market structure patterns known as “The Strat” setups, specifically focusing on 3-bar → Failed 2, 2-bar → Failed 2, and Failed 2 → Failed 2 (“Dragon’s Tail”) sequences. It is designed to help traders visualize potential reversals, trapped traders, and exhaustion points directly on the chart, combining price action, volatility, and volume metrics to grade signal strength.
Key Features:
3-Bar → Failed 2 (Tiered Scoring):
Detects a 3-bar structure followed immediately by a strict Failed 2 bar.
Evaluates the setup using four criteria:
3-bar range relative to ATR
Failed 2 close position relative to the 3-bar midpoint
Failed 2 body-to-range ratio
Volume relative to recent average
Assigns a tier (A+, A, B, or —) to indicate reliability, giving traders a graded view of signal strength.
2-Bar → Failed 2 (A+ Only):
Identifies strict 2-bar structures immediately followed by a Failed 2 bar.
Uses a similar evaluation system as 3→F2 but filters only for the strongest A+ setups.
Highlights signals where price shows strong directional rejection and high probability for reversal.
Dragon’s Tail – Failed 2 → Failed 2:
Captures consecutive Failed 2 bars in opposite directions, a classic trapped-trader scenario.
Signals both bullish and bearish sequences on bar close, helping traders spot potential quick reversals.
How It Works:
Uses ATR to contextualize bar ranges and volatility.
Incorporates volume averaging to detect unusually high trading activity that validates the strength of a Failed 2 setup.
Strict bar evaluation ensures only fully-formed, confirmed patterns are labeled, reducing noise and false signals.
Optional labels and alerts allow traders to track these structures in real-time or on bar close.
Practical Trading Use:
Ideal for spotting short-term exhaustion points, trapped traders, and reversal zones.
Can be used alongside liquidity zones, VWAP, and fair value gaps to refine entries and exits.
Traders can focus on high-tier signals (A+ / A) for higher probability trades, while lower-tier signals (B) indicate caution or context setups.
Customization Options:
Toggle visibility for each pattern type (3→F2, 2→F2, F2→F2).
Adjust ATR length and volume average period for different instruments or timeframes.
Alerts are available for all major setups, enabling integration with automated monitoring or manual execution strategies.
Summary:
The Strat Structure Engine + Trapped Traders script combines price action structure, volatility, and volume analysis to visualize high-probability reversal setups. By highlighting both strict pattern confirmations and tiered reliability, it provides traders with actionable insight into potential turning points, trapped trader scenarios, and high-conviction market moves without relying on external scripts or assumptions.
