This element of trading discipline is my most difficult. As a swing trader in futures, to look at a trade develop and hesitate to pull the trigger or be in a trade and hesitate to adjust stops according to your preset plan, these are difficult issues to cope with. Especially when you would have been more profitable had you went according to plan. I hated this nervousness of the stomach so much that I started a training program for myself to go over trading decisions I should have made according to plan, plug the $ figures in, and see what profits I would have had. Surprisingly, these little mental errors can cost a lot of profits. What I also try to do often is to train like a batter or golfer. Try to make the adjustment to your basic swing to get the desired effect under various conditions. Take historical data and trade 3 month periods. See if you come up with the same triggers, stops, profits each time. This helps me with confidence in my plan. Takes time but it works. They say all great performers get nervous just before going on stage. Guess we're no different. Much Success,
