@Viktor-No problem. I am enjoying this trading so much, I have no issue with sharing my experience. I keep the calculation very simple..7 out of 10 trades equals my 70% winning percentage. Even if a trade has a 70% winning percentage and then has a small negative profit, I will still use it. I just analyze each of the 10 trades to see if I can manipulate the stop loss and/or take profit to result in a better net profit. This is also when I use the optimizer in EA Studio to see if it comes up with similar results.
I maintain this process even after I go live. Once an EA loses more than 3 times out of 10 trades, I immediately pull it and replace it with a new one. I don’t want to take the chance that it will continue to lose and then perform better later. If it does, that’s nice and if I ever have to replace another EA for the same time frame and currency pair, then I can revisit it again. I’m very conservative in my trading, so risk management is very important to me. :)
