After many years of experience, I realized that losses are part of the proccess trading. Losses happen to the best traders. The best traders I know do not have a 100% win rate.
When I take a loss, I sit down in order to:
a) review the trade
b) learn from my loss
What do you do when you take a loss?
Just like you do, sit down and go through the trade again and see where the mistakes are. The only problem with checking back is that you have to be someone that is conversant with charts a lot so that when you see such type again in the future, you’ll be able to highlight as the same one that made you be on loss the last time you tried to trade it. What I do for setups like that is, I save the setups and when I want to take a new thread that I feel are similar to the previous ones that have exited me from the market before, I go back to the saved set up to confirm my claim whether I’m right or not about it. No one has 100% win rate and the best of those traders are the ones that accepts losses and take corrections from them to amend their upcoming trade with it.
