To judge yourself not on how much money you made today, but on how well you traded today. The following comes not from a trading book but from a poker book by Dusty Schmidt, who is a very good poker player. http://www.pokertableratings.com/stars-player-search/Leatherass9 http://www.pokertableratings.com/fulltilt-player-search/Leatherass9 Just replace the word 'playing' with 'trading': - How well you played overall - Quality of your thinking - Quality of decisions - Number and size of mistakes - Quality of focus ('the Zone') - Length of time spent focused and playing well - Length of the session [the two above are probably not relevant to trading] - Ability to manage emotions, focus and thinking - Ability to work through a tough mental or emotional spot
A combination of 1) Not caring about the results of individual trades I.e. Proper trade sizing AND 2) Believing (correctly) in your edge. Personally, I think this is the big one.
