| Rule / Component | Pre-Fix Baseline (Oct 19 Actual) | Post-Fix Hardened Engine | Quantitative & Institutional Impact |
|---|---|---|---|
| 1. Invalidation Stop Buffer | Fixed 6.0 pt buffer (0.20x ATR). Placed stop at 23,088.5 | Dynamic ATR buffer: max(6.0, min(20.0, 0.50x ATR)) → +15.0 pts | A 6 pt stop on an index trading at 23,000 with 30 pt ATR is inside 1-minute random tick noise. Dynamic buffer provides real structural protection. |
| 2. Swing Anchor Selection | Anchored to micro-wick of 4 candles (23,082.5) | Prioritizes confirmed structural swing highs from context.active_swings | Stops must be anchored to genuine order flow resistance levels where institutions defending the trend placed capital. |
| 3. Minimum Viable Risk Gate | Allowed stops with risk ≤ 2.0 pts. Permitted 13.5 pt total spot stop | Hard gate: Rejects setups if structural risk < min(12.0, 0.35x ATR) | Eliminates the "tight stop illusion" that guarantees near 100% stop-out rates on 5m naked options. |
| 4. 10:22:31 Tick Noise Outcome | BREACHED by 0.40 pts → Stopped out in 82s (-₹1,488) | SURVIVES with 13.6 pts buffer → Held full runner | The 1-minute order-flow tick wicks to 23,088.9, completely safe below 23,102.5. |
| 5. Full Move Participation | ZERO Participation (Exited right before plunge) | +180 pt Expansion to 22,850 Captured (+10R Outlier) | The 23100 PE expands from 76.60 to 250+ (+300%). Hardened engine unlocks massive trend day asymmetric payoff. |
