Establish your own investment/speculation framework. Each order must have its own logic. This is the source of your profit. Only in this way can you open up the pattern and hold it when you seize the opportunity. At the same time, you must also train your position management and stop loss awareness. This is the basis for cutting losses and retaining strength. In this way, you will not be hurt if you make mistakes.

Most people are familiar with three traditional methods of adding positions: pyramid (adding positions smaller and smaller), inverted pyramid (adding positions larger and larger), and uniform adding positions (adding positions the same each time);

Among them, pyramid adding positions tests your judgment of the market (the first position is the largest), while the inverted pyramid will increase costs and increase risks, and may hit the stop loss after a callback.

The fund management method shared in the book is the diamond adding position method. The market is favorable to you, increase your position, and the market callback will not cause greater losses because of the small position, which can play a role in smoothing the fund curve.
