How to Calculate Maximum Drawdown
Maximum drawdown refers to a significant trading measure of a maximum equity loss you’ve incurred in your portfolio. It’s a statistic that can be determined in backtesting and live trading. During backtesting, maximum drawdown reflects the downside risk of your trading strategy while in live trading it helps you identify instances when your strategy might be malfunctioning.
The value of a maximum drawdown (MDD) is expressed in percent and reflects the highest equity loss between peaks. To determine the MDD, you need to calculate your running percent profit and total loss and then utilize the Excel MIN function to find out the maximum drawdown, which refers to the lowest number.
