The method of locking an order is really useful. In case multiple orders are opened incorrectly, to prevent losses from expanding, a new short order can be used to compensate. If used well, it can even increase profits. The principle of this method is similar to U.S. Treasuries, which use future methods to solve present problems. The key to the success of this method lies in whether it can successfully solve the problem better in the future. Leaving the current problem for the future is the principle of locking an order. This is also a method of parallel universes, leaving the problems of this universe to another parallel universe version of myself to solve. $ETH $BTC
