1/ Lack of Discipline— a) Not sticking to one strategy, b) not respecting your trading rules, c) not sticking to your plan.
If there are other reasons why traders lose money, share them with me.
This particular advices are actually important to a trader but they do not stop one from losing rather we should say they minimize your losses. Traders can follow their own strategy and still be on a long losing streak but the importance of sticking to it is they help you to learn. That’s why one advice I will add is to trade few pairs and not just all pairs, try to have the culture of back testing your strategy on a pair multiple times first before going full in to trade them.
I don’t actually see using high leverage as a very big problem if at all you have a very good risk management. Even at a 100x leverage if your position size is well calculated you will not get into huge loose because you will have gotten your perfect stop loss.
This is a very serious problem to almost every trader, only the few disciplined traders can overcome this, the Euphoria of been on a winning streak can drive one to over trading. This is part of the reason why some traders even take off take profits and allow trades to move until some reverse back. I think this and revenge trading if overcome by a trader will solve more than half problems associated with trading physiology
Over trading can be when you trade multiple pairs just to gain more profits. Or you trade more than you use to, for example you usually trade two pairs a day but after they hit TP you go back to trade again or when you lose instead of opting out of trading you continue trading to recover losses there by surpassing your usual limits.
Some people can open ten trade positions at same time, this makes you not to study the trade well enough before executing them. This is my own opinion of over trading
