Have a limit, set a goal to achieve, and well, accept that anything you've started trading is already lost. Especially having a limit and a goal, those are especially important if you aim to trade in the long run. It wouldn't matter much if you're a rich kid aiming to become richer by trading since losses can be neglected cause of your rich-kid status, but if you aren't, losses are something you have to accept, you have to take in, and you have to understand. Don't avoid losses but rather study them and prepare measures to ensure that you won't turn crazy by doing so.
Sad, Regret, Sat at the corner, Sleep, Energized. Come back the other day - when I lose big.
Trading losses make me feel dehydrated and want to break for at least 24 hours. I will just allow those regrets and disappointment to come to me. After I came back to my feet, I will now analyze what's wrong. On what action I messed up. Then I will prepare again for a comeback.
But again, that only applies when I lose big. For those average losses, it can't really affect me at all. I called it just another day in the office.
Or you can just do this. Honestly most tips are absolute bs since most people have their own way of coping up to losses, even I can't handle my losses that well even though I follow the tips I just said. Bottom line is you should do something to make yourself calm down after losing so much. That's basically it. The way you do it isn't probably important, as long as you know, it doesn't go over line like killing people to calm down, but anyway, as long as you calm down, you can basically do anything. If trading after losing so much calms you down, you can do so tbh.
