I know many traders fail because a fatal error. after learning trading strategy and money management , there is a very important thing to be learned controls emotions. controlling emotions is part of trading psychology, and can be learned only in a real account.many traders successful in the demo account, but failed in the real account, this is a serious problem. traders is not enough just to learn in a demo account.
now I have a problem in real account, if I got the loss, then I would open position using a large lot size, I want to get a big profit, but what happened? I've got a big loss because my revenge. if I get a profit, then I open position again and again, and endless profits are down, even got a loss.traders should always keep emotions in order to always have a stable emotions, discipline on the rule of trading systems and money management
