Then there is the direction in which you should close your position, especially when you are not sure about the market. If you have made money, then Bian Xiao suggested:
First: you can close some positions first and earn a little first. Even if you lose the remaining market, you will make money before;
Second: Don't hesitate to close the position directly. You've made money anyway. The profit after liquidation is the most important thing, and there is always a chance to make money from trading orders. You don't have to worry about the market you can't grasp. You can always find the next opportunity to make money.
