In trading, one must never act out of emotional impulse. The two most common manifestations are particularly deadly.

The first is losing consecutively and then losing control out of anger, disregarding points, direction, or conditions, only thinking about trading continuously. "Anger is a venting of one's own incompetence"—this couldn’t be more fitting here. I was like this back in the day; after a series of mistakes, I began to doubt myself: Have I been wrong all this time? Can I not read the market at all? Has all my effort been for nothing? From unwillingness to anger, I traded frequently to prove myself, completely losing my rationality, resulting in devastating losses.

The second is hastily trying to recover after significant losses. In this situation, one can easily trigger a gambler's mentality, ignoring points, overestimating the success rate, and even recklessly increasing positions. At this time, trading is not based on rational analysis but rather on a heart eager to recover losses, and the outcome is predictable.

Emotional trading is the biggest killer of losses. If this problem can be resolved, and if every trade is rational, planned, and executed, then the winning rate of trades can increase by at least 30-50%.
