I watched a live broadcast of a big guy talking about positions, and I share it with you to learn on your own.

My current advice on position management: For example, if you take out 30,000 U to make a contract, my suggestion is to divide it into 3 parts, 10,000 U each. Use one of them to open a position each time, with a fixed 10,000 U, no more than 10 times for big cakes, and no more than 5 times for copycats. If you lose money, for example, you lose 1,000 U, you buy 1,000 U from outside, and if you make 1,000 U, you withdraw 1,000 U. Make sure that every time you open a position in the recent period, you can guarantee a fixed position of 10,000 U. Until you make 60,000 U in this way with 30,000 U, increase your position to 20,000 U, and do it this way.
