Quantitative evaluation reveals that session filtering for gold short trades suffers from severe sample size overfitting, suggesting negligible to negative impacts on overall portfolio returns.
DECISION: REJECT ELEMENT: The NY_OPEN + 5 conf filter for XAUUSD SHORT fails the hostility test — n=12 is not a sample, it's a rounding error. A single trade flip changes win rate by 8.3pp. No concrete, testable edge survives. EXPECTED IMPACT: Negligible to negative. Even if the 58.3% win rate held, the filter would cut trade count by ~60% (pre-NY shorts eliminated), reducing total PnL throughput. The 26.7pp win-rate gain is illusory without R-multiple or profit factor data. RISK: Overfitting to a specific time window (NY open) that is regime-dependent. Rejecting Asian/London XAUUSD SHORTs could miss high-R moves during low-liquidity spikes. The filter also conflicts with E8's rhythm logic, which is session-agnostic. TEST: Run a 90-day shadow replay on all XAUUSD SHORT signals (minimum 30 filtered trades). Require: win rate >50%, profit factor >1.5, and average R-multiple >0.8. If any metric fails, discard permanently. Author: Andrew Stewart Caldin, Independent Researcher, UK. Part of the E8 Intelligence Research series. Platform: e8intelligence.com
