Trading and light positions. There are three key points in trading: first, direction, second, entry position, and third, execution. The direction is judged by the system, there is nothing good or bad, right or wrong. The entry position can only be vaguely correct, not absolutely correct. The difficulty in execution lies in the mentality. A good mentality comes from confidence. The position is light. If you enter the market wrongly, you can still enter again. The cost of trial and error is small. Only with a light position and a good attitude can you dare to open a position and hold the order. Many people say that only by taking heavy positions can you make money. The benefits of taking heavy positions are obvious, while the disadvantages of taking heavy positions are only known to those who have made huge losses. It is undeniable that someone can control a heavy position, but whether that person is you or not is the key. The most valuable thing about people is self-awareness.
