What do you do when you exit a losing trade?

i would review the market direction to understand the reason, since usually there is Stop Loss, which something you should always put, on the trade so that’s acceptable loss and it impossible to win all trade anyways.

@Johnscott31. I can’t say that Agree with you on not looking for what you may have done wrong.
In fact, it’s the best way to learn more about your self and to learn from your mistakes.

When you’ll learn from your mistakes, you will never commit that mistake again in your trading.

agreed the reason why they think they fail is because of looking for short term success

Taking time off and find out what went wrong, providing of course if you have trading journals with you.
