Why do so many people lose money playing contracts???

1. Frequent position opening operations
2. The mentality is unstable, and a little fluctuation will change direction
3. Lose money, will not adjust positions, and make profits and can't hold orders
4 Open this today, open that tomorrow is not dedicated enough, and you can't grasp the market trend
5 You can't make a lot of money, you can't make a little money and you don't have the patience to look down on small money,
6 I want to make a lot of money, I feel that I can get a stud right, and I don't have a chance for myself,
