Drawdown measures the worst stretch of a session, not where it ended. A session can finish only slightly down but contain a deep drawdown in the middle - and deep drawdowns are when people start chasing losses.
Example. You start with $100. You climb to $130, then slide to $78, then recover to $95.
- Peak: $130. Lowest point after the peak: $78.
- Drawdown: $52, or 40% of the peak.
- Final result: −$5. The ending number hides how rough the session felt.
Median vs max drawdown. Across many simulated sessions, the median drawdown shows a normal session's worst stretch. The max drawdown shows the worst stretch any session hit. High-risk settings and progressive betting systems push both up sharply.
