Actually, before I enter trading, I always tell myself that I have to be mentally ready and stable in what will I do because I know that there is a possibility that I will lose my money if I handled it incorrectly. In that way, I set my mind that there is always a possibility that I might lose what I have right now and I have to refrain myself from overreacting because instead of analyzing what I have done wrong, I might just commit another mistake that I'll surely regret. Not just in losing, but also when winning. I also tell myself to not overreact frequently especially when winning because I might do uncertain things that instead of securing money, i will lose it. You just have to know and understand your emotions and you just need to be able to control it in order for you to handle it properly.
