⏸️ Strength BUY DISABLED · 2026-07-09 9-day audit:
· Backtest result: 6 historical signals, 2W/4L (33% WR, -1.31% avg)
· Why it failed: thesis inverted — stocks already up +5% in 5 days + LLM 樂觀 = TOXIC BUY territory. 7/6 META/HOOD/PANW/PDD/MDB/TTWO all dropped next day.
· Lesson: never BUY when sentiment = 樂觀 AND multi-day gain exists. Buying strength at top = catching falling knife.
· Replacement: Conservative BUY v2 (anti-chase overlay) + Bounce BUY (mean-reversion) cover the same intent without the trap.
· Re-enable trigger: > 5 consecutive paper-trade wins OR re-design with mandatory pullback (chg≤0 today).
