In the book 'Trading in the Zone' which really is about the psychology of money management, Mark Douglas gives a test for any trading system. Use the exact system for 20 trades. Trade 2% of your account balance on each trade. At the conclusion of 20 trades, if you have not made a profit, you don't have a trading system. So 90 trades later, I'm down 1.4%(**) so it is time to pull the plug. Thankfully this has excellent money management and for that reason the account still has 98% of the balance. But, it isn't making money. So either the mathematics behind the book are flawed or this EA is not going to achieve its stated objectives of 10% or more per month.
(**) This system was started on March 1 after the account had lost 9% from previous trading.
