We can't really get rid of emotions because we are human beings and its a part that of us. But for me the best way to do is try to relax,chill a little bit and don't over think too much and don't risk everything. Keep calm,control your emotions.
It is not about getting rid of them, but if you look at great performers you will see that even under the greatest pressure they are able to perform their best, this is not easy at all since most people have the same capabilities to perform when they train but when it counts they are unable to perform as they should, and you need to have the same endurance if you want to be a good trader.
