Most traders underestimate the risk of blowing their account. Unfortunately, this is a real risk that many people experience every year.
There are a number of steps that you can take to avoid the risk of ruin. One way to test the robustness of your trading strategies is to use a Monte Carlo simulator. Once you have done a backtest, you use the simulator to see how it affects your maximum drawdown. The simulator uses random numbers to re-order your trades and will show you how high your drawdown could be.
This model is easy to use. Firstly copy in a list of trades, select the number of iterations and click the button.
