![]() This will provide you with data that will help you understand what you can expect in live trading. It is recommended that you calculate your maximum drawdown in backtesting. The same process can be used to calculate the MDD for your portfolio by entering each of your portfolio trades in the spreadsheet. How do You Find Max Drawdown of a Portfolio? Regardless of whether you have a new peak in your account balance, if your current drawdown is larger compared to earlier drawdowns, that’s your MDD. Given that MDD is calculated in percent, you need to find out the percent change for every trade.Įnter the percent profit/loss in the following column to calculate a running total.Īfter you’ve created a running total in percent, use Excel’s MIN function to identify the lowest number in the column to calculate the maximum drawdown.Īs you can see, the formula used in this example is: =MIN(t3:t17) ![]() ![]() You can see the formula in the image below.Īfter that, create a percent profit or loss for every trade in the following column. Then, make a new column and enter the profit from each trade to the running balance. Navigate to File > Import and import your file into Excel. In this example, Forex Tester was used to examine backtesting results. You can also use other similar softwares such as Google Sheets or Mac Numbers. 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.īelow, you can see a step by step guide on how you can calculate MDD in Excel. The value of a maximum drawdown (MDD) is expressed in percent and reflects the highest equity loss between peaks. 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. It’s a statistic that can be determined in backtesting and live trading. What might help is a sample data set that includes the transitions I describe, with your expected results manually calculated so we can test our formulas against your expected answer.Maximum drawdown refers to a significant trading measure of a maximum equity loss you’ve incurred in your portfolio. ![]() Then you want to determine which of those drawdowns was largest in percent of it's high. During an upturn you will have a number of small subsets on each brief up-down-up cycle. During a downturn, you will have a single large subset unaffected by temporary upturns, or even sustained upturns that fail to reach the previous high. If an upturn is interrupted by a short period of decline, the minor drop will result in a new high, a new low, then a transition above the latest high. The next subset won't begin until a new high is set, so the data accumulated during an uninterrupted upturn from one high to the next is ignored. You want to calculate drawdowns for multiple subsets of the continuous data, with each subset starting at a new high and ending when that high is reached/exceeded following a downturn. Here's the problem as I understand it correct me if I'm wrong: ![]()
