Probability Breakdown: Empirical vs. Theoretical Models
Comparing actual market back-data against Black-Scholes and Fat-Tail adjustments.
| Model / Methodology | Touch Probability | Expiration Close Probability | What It Tells You |

| Standard Normal (Black-Scholes / GBM) | 7.2% | 3.6% | Classic theoretical log-normal model with constant volatility (often underestimates tail risks). |
| Regime-Conditioned (Similar Volatility) | 4.5% | 3.4% | Filters for historical windows that started with volatility similar to current 20-day HV (292 matching periods). |
