Truly speaking is very difficult to control and restrain my emotions and probably most of the times I can not. Maybe I have to be trained to be cool in some way and perhaps the the best option is to set goals in profit and loss and follow them every time
There is no way you can train yourself to completely control your emotions. We are humans driven by instinct and intuition. Unless you want to be emotionally dead you'll have to experience emotions from time to time. Nothing wrong with that.
As for setting up goald and stop-losses that's a good thing, does not mean you have to stop feeling happiness or sadness though.
