I downloaded a trading analysis program; which allows you to analyse statistically trading systems and or your trades. I will have to test it a bit and report some of my results here. I never looked at these things thoroughly because I am not a system trader so, so these things never bothered me that much. Maybe I look at things a different way in a sense becoming more a systematical trader but I clearly have a long way to go.
