A simplified estimate of how your win rate and risk-per-trade combine to put your account at risk — useful for comparing settings, not as an exact forecast.

Estimated risk of ruin0.0%
This uses a simplified model that assumes a roughly 1:1 reward-to-risk ratio and a constant win rate across every trade — real trading rarely holds either assumption exactly. Treat this as a rough sensitivity check on risk-per-trade, not a precise prediction of ruin.
