Bug: les markers BUY/SELL du chart utilisaient les timestamps des trades du backtest mais les candles étaient fetchées séparément (500 candles récentes), causant un désalignement visuel. - Backend: /backtest retourne désormais les candles exactes du DataFrame analysé - Frontend: Backtest.tsx utilise result.candles directement (suppression du fetchCandles séparé) - Ajout: sérialisation reason/OB/LL sur les trades, overlays OB/LL bornés dans le temps, trade reasons expandables, filtre HTF, badge tendance HTF Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
