LAB #2515 NEUTRAL: LEDGER BENCH: Apply filter: BTCUSD LONG — improves win rate from 31.1% to 39.2% (+8.2pp, n=51) — E8 Intelligence Research

IDEA: Adjustment made to the live model — verify against the backtests: Apply filter: BTCUSD LONG — improves win rate from 31.1% to 39.2% (+8.2pp, n=51) SAME-WINDOW EFFECT: Over the current live window, applying a BTCUSD LONG filter would have had **zero direct effect** — none of the 10 listed trades are BTCUSD, and the filter does not alter entry logic for other instruments. The only indirect impact would be if the filter is meant as a market-regime gate (e.g., only trade when BTCUSD is in a long trend), but as stated it is a symbol-specific filter, so no trades in this window would be added or removed. Therefore, the claimed +8.2pp win-rate improvement from backtest (n=51) cannot be validated or refuted against this live sample — it is a non-event here. PnL delta: $0. OVER-TIME PROJECTION: Over 3–6 months, a BTCUSD LONG-only filter would likely reduce trade frequency significantly (BTCUSD is not a dominant symbol in your current set), which could improve win rate by cherry-picking Author: Andrew Stewart Caldin, Independent Researcher, UK.
