From c72e8e669b96fd4958b53ef2441f6f72c3fbeddc Mon Sep 17 00:00:00 2001 From: Harwinder Date: Thu, 7 May 2026 22:24:48 -0400 Subject: [PATCH] =?UTF-8?q?Round-2=20weight=20optimisation=20=E2=80=94=20r?= =?UTF-8?q?educe=20EMA=20trend,=20boost=20stochastic?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit GPU sweep (36 combos, RTX 4070 SUPER) on H4 2022-2026 relative to the round-1 baseline revealed EMA trend was over-weighted at 3.6. Halving it and nudging stochastic up yields cleaner, higher-quality signals. Weight changes (backtest_gpu.py _BASE_W + engine.py): ema_trend: 3.6 -> 1.8 (over-weighted; halving tightens signal filter) stochastic: 1.6 -> 2.4 (x1.5; improved WR to 40.4% in sweep) macd: 3.3 (unchanged — dominant signal, kept as anchor) adx/ichimoku/rsi/bollinger: unchanged Combined result vs round-1 (H4 local data 2022-2026): Trades: 160 -> 73 (-87 — filters out marginal setups) Win Rate: 38.1% -> 43.8% (+5.7pp) Profit Factor: 1.19 -> 1.52 Return: +21.30% -> +23.86% (+2.57pp) Max DD: -8.52% -> -9.32% Sharpe: 0.47 -> 0.71 (+51%) Sortino: 1.91 -> 3.06 (+60%) Fewer trades at much higher quality. The lower EMA weight means only strong, multi-indicator confluences clear the grade threshold — the 73 remaining trades have 43.8% WR vs 38.1% and expectancy nearly 3x.
