If you have a name for each of your tested setups, it makes it easier to keep your error log current.
If your setups have triggers, it makes it easier to keep your error log current.
If you review your error log once a week, it makes it easier to single out the most costly mistake, isolate it, diagnose it, get your head right and move on.
If you do this for a half a year, it makes it easier to weed out recurrant errors and move on to being a rules based trader.
If none of this works for you, then you may not be a rules based trader at heart and the sooner you recognize that the sooner you can become an artistic intuitive trader, but I've yet to see the detailed plan of action for that other than step one which is to be prepared for years of pain?
