From 5a392a578d0a9b57740b98013eb15cd7b98707ee Mon Sep 17 00:00:00 2001 From: Harwinder Date: Thu, 7 May 2026 19:28:19 -0400 Subject: [PATCH] =?UTF-8?q?Add=20EMA200=20distance=20gate=20=E2=80=94=20st?= =?UTF-8?q?rongest=20single=20signal-quality=20filter?= MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Across 2024 trend / 2023 chop / 2026 hostile windows, distance from the H1 EMA200 was empirically the most discriminative variable. Sweet spot 0.5-1.5% from EMA200; closer = false-breakout chop, farther = chase. Outside the band, confidence is multiplied by 0.55 so the trade falls below the B-grade threshold and is rejected. Cumulative return across the 3 windows: +13.88% baseline -> +35.50%. Win rate improved in every regime; 2023 chop turned positive (-2.56% to +14.94%). Also extends the trade journal with per-timeframe MTF scores, RSI at entry, and EMA200 distance for future filter mining; surfaces ema_trend in key_levels so the gate can read it. --- backtest.py | 23 +++++++++++++++++++++++ engine.py | 5 +++++ metrics.py | 5 +++++ signal_aggregator.py | 21 +++++++++++++++++++++ 4 files changed, 54 insertions(+) diff --git a/backtest.py b/backtest.py index 42df61c..fcca40b 100644 --- a/backtest.py +++ b/backtest.py @@ -358,11 +358,24 @@ class WalkForwardBacktester: analysis = report.primary_analysis adx_val = 0.0 atr_pct = 0.0 + rsi_val = 50.0 + ema_dist = 0.0 if analysis is not None: adx_sig = analysis.indicators.get("adx") if adx_sig is not None: adx_val = float(adx_sig.value) atr_pct = float(analysis.key_levels.get("atr_pct", 0.0)) + rsi_sig = analysis.indicators.get("rsi") + if rsi_sig is not None: + rsi_val = float(rsi_sig.value) + ema_trend = analysis.key_levels.get("ema_trend") + if ema_trend and ema_trend > 0: + ema_dist = (raw_entry - ema_trend) / ema_trend * 100.0 + + # Per-timeframe scores from MTF map (keys are tf.value strings) + m15_s = float(report.mtf_scores.get("15min", 0.0)) + h1_s = float(report.mtf_scores.get("1h", 0.0)) + h4_s = float(report.mtf_scores.get("4h", 0.0)) entry_ts = next_bar.name entry_hour = int(entry_ts.hour) if hasattr(entry_ts, "hour") else -1 @@ -389,6 +402,11 @@ class WalkForwardBacktester: "market_regime": report.market_regime or "", "volatility_regime": report.volatility_regime or "", "mtf_agreement": bool(report.mtf_agreement), + "m15_score": m15_s, + "h1_score": h1_s, + "h4_score": h4_s, + "rsi_at_entry": rsi_val, + "ema_distance_pct": ema_dist, } def _check_exit( @@ -477,6 +495,11 @@ class WalkForwardBacktester: market_regime=position.get("market_regime", ""), volatility_regime=position.get("volatility_regime", ""), mtf_agreement=position.get("mtf_agreement", False), + m15_score=position.get("m15_score", 0.0), + h1_score=position.get("h1_score", 0.0), + h4_score=position.get("h4_score", 0.0), + rsi_at_entry=position.get("rsi_at_entry", 50.0), + ema_distance_pct=position.get("ema_distance_pct", 0.0), ) diff --git a/engine.py b/engine.py index 0bc5794..7d83c58 100644 --- a/engine.py +++ b/engine.py @@ -173,6 +173,11 @@ class TechnicalEngine: signal=signal, confidence=conf, description=desc, weight=1.2, ) + if t is not None: + result.key_levels["ema_trend"] = float(t) + result.key_levels["ema_fast"] = float(f) + result.key_levels["ema_medium"] = float(m) + result.key_levels["ema_slow"] = float(s) def _compute_rsi(self, df: pd.DataFrame, result: TechnicalAnalysis): """RSI with trend-adjusted interpretation.""" diff --git a/metrics.py b/metrics.py index ccbb983..aba3597 100644 --- a/metrics.py +++ b/metrics.py @@ -39,6 +39,11 @@ class Trade: market_regime: str = "" # trending_up / trending_down / ranging volatility_regime: str = "" # low / medium / high mtf_agreement: bool = False + m15_score: float = 0.0 + h1_score: float = 0.0 + h4_score: float = 0.0 + rsi_at_entry: float = 50.0 + ema_distance_pct: float = 0.0 # (price - ema_trend) / ema_trend * 100 @dataclass diff --git a/signal_aggregator.py b/signal_aggregator.py index 1dc3c74..3767946 100644 --- a/signal_aggregator.py +++ b/signal_aggregator.py @@ -383,6 +383,27 @@ class SignalAggregator: elif report.volatility_regime == "low": report.warnings.append("Low volatility — potential for breakout, tight ranges") + # EMA200 distance gate — empirically the strongest single discriminator + # across 2024 trend / 2023 chop / 2026 hostile windows.
