The same thing greed and fear is an emotion. Our success is stuck here. If you say why? However, I would say that many traders continue to trade without a goal, even if the investment doubles in a month, they are not satisfied, they want more and this demand makes their investment zero.Emotion can not save our trade. Its only can make our poor trader much worse. Though some folks says that greed, panic etc.. these sort of emotions can be utilized as positive way, but I feel that it is not feasible to become successful trader having these feelings, we should try to prevent them while trading.
