People always think that they will make a profit before trading. They want to make a profit and think that they will make a profit, which will lead to the final trading behavior. Foreign exchange is traded 24 hours a day. No matter whether the last order is profitable or losing money, you still think that the next order will be profitable. It is this idea that keeps you trading until you can't trade in the end, or you can't wake up from day trading. It's that you use foreign exchange as a game to practice how to control losses.
