LAB #2301 NEUTRAL: LEDGER BENCH: Apply filter: EURUSD LONG — improves win rate from 31.5% to 34.8% (+3.3pp, n=46) — E8 Intelligence Research

IDEA: Adjustment made to the live model — verify against the backtests: Apply filter: EURUSD LONG — improves win rate from 31.5% to 34.8% (+3.3pp, n=46) SAME-WINDOW EFFECT: Applying a EURUSD LONG-only filter would have zero impact on the current live window — none of the 10 listed trades are EURUSD, and the filter does not alter entry logic for other pairs. The claimed +3.3pp win-rate improvement (n=46) is statistically fragile (standard error ≈ 7.1pp), so the observed gain is within noise. PnL delta over this window: $0.00. OVER-TIME PROJECTION: Over 3–6 months, this filter would only affect EURUSD LONG signals, which are a small subset of your overall flow. If the backtest edge is real, it could add ~1–2% net win-rate on that pair alone, but the risk is overfitting to a specific regime (e.g., EURUSD trending up during the backtest window). The filter does not address the dominant loss driver (XAUUSD shorts, 3 losses in window) and may reduce trade frequency without improving risk-a Author: Andrew Stewart Caldin, Independent Researcher, UK.
