I'll let you in on a secret: next time you want to open more positions, think about the worst-case scenario, and then open at the worst point. This will significantly increase your win rate.

Is there a big brother who can save me? I don't have much capital left. I don't know why they always target my money. Every time I go short, it rises; every time I have a lot, it goes short. I held long positions for two or three days, and today I wanted to go short and closed my position, and it immediately skyrocketed. Why?
