Forex is a zero sum game and we traders should not expect that we never face losses. A world market won't be completely risk free. So; it is the responsibility of us to ensure the right mind set of trading. In any case if we lose; we should try to identity mistake and take it practically instead of giving up. I try my best to handle my emotions like antagonism, aggravation, ravenousness, etc. so that I can maintain rational decision making and without being emotional I can handle any situation.
