I am very good about getting out of trades that are going bad. I often even end up with small profits a few $ over commissions. My big problem is hanging on to winners long enough.
When I average all my winners, and losers together, I found that I have an average win of $84.00 per contract. My losers are about as small as I can possibly make them, without missing winning trades. But when I look at all my winners, I see that I could have made more if I learned to hold on just a bit longer.
