Maximum Adverse Excursion

Maximum Adverse Excursion is a risk management metric that tracks the greatest loss a trade experiences at any point between entry and exit, even if the trade ultimately closes at a profit. By analyzing the MAE of historical trades, a trader can determine if their stop-loss levels are too tight or too wide relative to the natural price noise of the asset.

It provides deep insight into market microstructure, revealing how much price drawdown is normal before a trend resumes or a reversal occurs. Understanding MAE helps in refining exit strategies and improving the accuracy of risk-constant sizing models.

It is particularly useful in cryptocurrency markets where liquidity gaps can cause temporary price spikes that trigger stops unnecessarily. Using MAE data allows for more robust, data-driven adjustments to trade management.
