1. If it is in the early stage of the upward trend and is at a historical low, you should not close your position when you withdraw your position, but you can also add your position and wait for it to continue to rise.

2. If it is in the middle of the upward trend, the situation is more complicated. It can be predicted whether the market will continue and whether there is a possibility of reversal, so as to decide whether to partially close the position, completely close the position, or increase the position.

3. If there is a position retreat at the end of the upward trend, we should be highly vigilant. This is probably the beginning of a downward trend. No matter whether the market continues to rise in the future, you must close your position immediately, because if the market continues to rise, you can enter the market at any time. At least, you should close most of your positions, leaving only a few positions, and be ready to close your position at any time to cope with the possible next decline.

The above is an example of long futures, and vice versa.
