Risk of ruin

This metric quantifies the likelihood of depleting an entire trading account based on a trading strategy's characteristics. It is typically calculated using mathematical models that consider factors such as the strategy's win rate, average profit per trade, average loss per trade, and the total capital available. A higher risk of ruin indicates a greater chance of losing all funds.

For a retail trader, understanding the risk of ruin is crucial for long-term survival in the markets. It underscores the necessity of robust risk management and appropriate position sizing for each trade. Ignoring this probability can lead to the complete loss of invested capital, making it impossible to continue trading. Managing this risk is key to sustained participation.
