"do not try to learn a lesson"??? This is flat out bad advice. One should always be looking to improve by analyzing a failed trade... the goal is to determine if the trade was truly a "bad" trade-- one that after being detached from it allows you to see where you potentially violated your setup/trade plan rules. The ideal outcome from analysis will be finding out that you traded the perfect setup... it simply did not work out. When you lose-- you want to lose on your best, highest probability setups. And you want to take those same setups as they arise over and over and over... with no regard for the losing trade.... for you realize trading is all about probabilities and if your setup is sound... more often than not the perfect setup will be a win... not a loss. what you DON'T want to do is continue to make "bad" trades... this is a recipe for failure. The only way to determine if the trade is truly "bad" is to analyze it... record it in a journal and the lesson learned from it.... with future review in mind.
