Markers (%B = candle position within BOLL(20,2.5); red/green dot = triggered on any leg): 🔴 C1 near upper band (%B≥0.8) → DOWN · C3 near mid (0.45~0.55) — avoid (solo success 76~78%; removing them adds +5.4pp to plan success); 🟢 C2 near lower band (%B≤0.2) → UP — bonus (100% in backtest, matches lower-band-break reversal); 🟡 Edge entry %B in 0.55~0.8 or 0.40~0.45 — high mid-leg breakout risk (17~26% historically), but data supports continuing the chain after breakout (post-breakout leg hit-rate unchanged) · accumulating, to be re-validated
