There are two common ways to deal with retracement. One is to ignore the fluctuation of the market after opening a reasonable position, and the other is to open a position by rolling and change the cost of capital according to the market.

If we use the second method, we need to grasp the reversal and deviation of the market in real time, and we need to be more skilled in the application of K-line shape and technical indicators and have plenty of time.

Therefore, it is suggested to use the first method to fix the position, first determine the maximum risk you can bear, determine the maximum withdrawal rate, and then plan your position size.
