Tune engine from backtesting: wider SL, capped TP, counter-trend filter
Backtest-driven fixes (0% win → 33% win, PF 0.00 → 1.05 over 7 days): - SL: swing buffer 0.5→1.0 ATR, min distance 1.0→1.5 ATR (more room to breathe) - TP: cap swing targets at ATR×3.0, fallback ATR×2.0 (was targeting unreachable levels) - Mature-move TP: when score>30 (A/B grade), tighten TP to ATR×1.5 (move already extended) - Counter-trend penalty: -15 confidence when signal fights regime direction - EMA200 penalties halved: -20→-10 (was killing EUR/USD signals) - Score thresholds lowered: BUY/SELL ±15→±12, STRONG ±40→±35 - Quality grades relaxed, C-grade now gets trade setups and Telegram alerts - min_rr_ratio: 1.5→1.2 - Gitignore backtest/ directory Co-Authored-By: Claude Opus 4.6 <noreply@anthropic.com>
