Aroon-OB Structural Expansion Strategy

Family: trend_following · Regime: trending · Complexity: high · Asset classes: Forex, Equities, Crypto · Timeframes: H1, H4, D1

Thesis

The strategy hypothesizes that trends are not smooth but move in impulsive 'steps' identified by Fair Value Gaps and Order Blocks. By entering only when the Aroon indicator confirms a strong directional bias and momentum is verified via historical UDT referencing, the trader captures the high-probability expansion phase of a move. The use of Heiken Ashi ATR provides a more robust volatility filter that ignores minor noise, allowing for wider, more logical stop placements relative to synthetic price swings.

Components

• Unsupported array abs label method (regime) — Used as a 'Logic Runtime Filter'. In this strategy, it represents a pre-flight check that ensures the execution environment can handle complex array operations before allowing trade execution.
• Aroon (direction) — Identifies the primary trend direction by measuring time since the last high/low. Ensures entries only occur during established trend phases.
• Order Block / FVG Detector (entry) — Acts as the trigger mechanism, identifying institutional liquidity gaps (Fair Value Gaps) or accumulation/distribution zones (Order Blocks) for high-probability entries.
• Commodity Channel Index (CCI) (exit) — Used to detect momentum exhaustion. Exits are triggered when the price deviates significantly from its statistical mean and begins to revert.
• ATR Heiken Ashi (risk) — Provides a smoothed volatility measurement using Heiken Ashi synthetic price data, used for dynamic stop-loss placement and position sizing.
• Imported UDT Typed UDF Params Test (confirmation) — Confirms the validity of the trend by checking historical references ([]) within a User-Defined Type object, ensuring current price action is distinct from historical 'points' stored in memory.

Known failure conditions

• Price action remains within the FVG/OB zone for extended periods without impulsive departure (failed expansion).
• Aroon Up and Down values both remain below 30, indicating a complete lack of trend.
• The ATR HA volatility drops below a minimum threshold, rendering the OB/FVG patterns statistically insignificant.
