After making sure that the phone was not held upside down, I checked the parameters on the computer... It is now 27900!
Here I want to share how to stop losses:
The first step is to directly close 1/3 of the short orders...
The second step is, if it falls to 27,600, close half of the position... If it reaches 28,000, close half of the position... If it goes above 28,500, stop the loss strictly...
