USDX-Gator Structural Scalper

Family: hybrid · Regime: trending · Complexity: high · Asset classes: Commodities (XAU/USD), Forex (Major USD Pairs) · Timeframes: M15, H1

Thesis

The US Dollar Index (USDX) acts as the primary gravitational force for XAU/USD. Market efficiency is highest when USDX trends are confirmed by volatility expansion (Gator) and immediate momentum (Bulls Power). By entering on mean-reversion extremes (Restu Kaioh) only when price action 'structure' is historically persistent (Linefill), we capture the high-velocity portion of the gold/dollar inverse correlation cycle.

Components

• Linefill Array Slice History Test (regime) — Serves as a 'market memory' regime filter; trades are only permitted if historical price levels (represented by the linefill array slice) have maintained persistence within the script's memory buffer, indicating a structured market rather than pure noise.
• USDX (US Dollar Index) Tracker (direction) — Determines the macro-trend direction. Since XAU/USD is inversely correlated with the USD, a bullish USDX MA cross dictates a bearish bias for the target asset.
• Restu Kaioh Scalping Indicator (entry) — Provides the tactical entry trigger based on Stochastic overbought/oversold states, treated here as local momentum exhaustion signals within the larger trend.
• MultiKAMA (TyphooN) (exit) — The adaptive nature of KAMA allows for an exit strategy that tightens during high-efficiency moves and widens during noise, protecting profits during trend reversals.
• Average True Range (Standard MQ4) (risk) — Used for volatility-adjusted stop loss placement and position sizing to normalize risk across varying market conditions.
• Bulls Power (Elder Ray) (confirmation) — Confirms that the immediate buying/selling pressure aligns with the macro USDX direction.
• Gator Oscillator (volatility_filter) — Acts as a volatility expansion filter; entries are only allowed when the 'Gator is eating' (green bars on both sides of the zero line), ensuring we don't scalp in dormant markets.

Known failure conditions

• USDX loses its historical inverse correlation with XAU/USD (e.g., during extreme global liquidity crises).
• Gator Oscillator remains in 'sleeping' phase for extended periods, leading to total signal starvation.
• The Linefill Array Slice fails to provide persistent historical coordinates due to high-frequency price churn.
