Risk of Ruin Simulator
Run a fast client-side simulation to see how risk per trade, win rate, payoff, and sample size can produce drawdown pressure even when the average setup is positive.
Deterministic simulation. No external calls.
Simulate repeated trades
Ruin means the simulated equity curve breaches the drawdown threshold at least once.

A trader can be directionally right and still fail a risk limit through clustering losses. Use the simulator to decide whether the planned risk per trade leaves enough room for variance, then compare the assumption against actual journal streaks.
