Compounding & drawdown calculator
See how risk per trade, win rate and reward-to-risk compound over time, and how much you need to recover from a drawdown.

Losses compound against you
A 10% loss needs an 11% gain to recover, a 50% loss needs 100%. That asymmetry is why risk per trade matters more than any setup.
Expectancy
Expectancy = win rate × R − loss rate. If it is positive, small consistent risk lets it compound; if it is negative, no position size can save it.
