These "Trade statistics" are attempt of me to to give life to the report that you normally see after backtests, and it's something that I'm not proud of 🙂 So, this is global. When DD is calculated to be 20%, it will remain at least 20% until the end of the EA. DD is calculated as the difference between the top Equity/Balance that was reached and the bottom Equity/Balance that was reached after that top. If you can do it in a different way, do it. Mostly because these statistics slows down the EA and I am even thinking about removing them.
