I manage my emotions by talking to my self alone when I feel relaxed. Asking myself if what I have done is wrong or right. After talking to myself, I will realize what should I have done and what shouldn't be done.
Well, what's important is we can calm down ourselves, we have different ways in managing our own emotion since if we cannot manage it right it will make us lose a lot of money because we will be aggressive in trading without employing the proper strategy that we have plan beforehand.
That's what I'm trying to do while doing stressfull trades on the screen. I sometimes lose the control and can't control my emotions. They cause some mistakes and they become the reasons of the mistakes.
