Matrix-Fisher Momentum Scalper

Thesis

This strategy hypothesizes that market trends are most exploitable when price dispersion (STDERR) is low relative to momentum (QQE). By filtering for 'clean' trends using a Matrix Sort of recent prices and ensuring that volatility pressure (XAU_TVF) is not excessive, we can identify high-probability momentum pulses. The exit via Fisher transformation capitalizes on the cyclical nature of these pulses, exiting before the inevitable mean-reversion occurs.

Components

• XAU Trend Volatility Filter (XAU_TVF) (regime) — Filters out 'noisy' volatility (high VolPressure) while identifying established trends (high TrendScore). Sets the global bias.
• Matrix Sort Method UDF Test (direction) — Used to confirm price action order; a long bias exists if the current close is in the upper quartile of the sorted matrix of recent prices.
• Qualitative Quantitative Estimation (QQE) (entry) — The primary momentum trigger; uses smoothed RSI and volatility bands to capture local momentum bursts within the larger trend.
• Fisher-based Scalping Indicator (exit) — Identifies cyclical exhaustion. Used to exit positions as the momentum pulse starts to decay (Fisher reversal).
• Standard Error of Regression (STDERR) (risk) — Provides a measure of price 'tightness' relative to a linear trend. Used to define stop-loss distance and scale position size.
• Spread Display and Alert (volatility_filter) — Acts as a liquidity gatekeeper; prevents entries during high-slippage/low-liquidity periods that would invalidate the scalping edge.

Known failure conditions

• Prolonged periods where VolPressure remains above 2.0 while TrendScore remains near 0 (volatility without direction).
• When price exhibits high-frequency oscillation within a range smaller than the average Spread.
• Persistent 'fat-tail' price events that invalidate the linear regression model used for STDERR.
