Risk of Ruin is the statistical probability that your trading account will drop to a level where you can no longer trade (or hit a prop firm's max drawdown limit). By modeling your win rate and risk percentage, you can ensure your Risk of Ruin is near 0%.
Losing streaks are a statistical certainty. Even with a 60% win rate, you will inevitably face 5 or 6 losses in a row. Risk modeling helps you visualize how deep your drawdown will be during these inevitable streaks so you can size your trades accordingly.
Fixed percentage risk is generally superior because it automatically scales your position size up as your account grows, and scales it down during a drawdown, helping to preserve capital when you are losing.
