About this app

Twelve hundred Monte Carlo runs of a win rate, a reward-to-risk ratio and a fractional bet size, reporting the probability of hitting a chosen drawdown, the median and tenth-percentile ending equity, and a table of how ruin changes with position size. Forty individual paths are drawn faintly so the dispersion is visible. Separates the two failure modes explicitly: a negative expectancy that no sizing can fix, and a real edge on an account that does not survive to collect it.
