Everyone is shouting for cows, right? Let me pour a bucket of cold water. There are too many dead cat jumps and rebounds in bear markets, so I have always said that it is difficult to do long or short in bear markets 1. The Air Force has accumulated a lot, and if they have a slight emotional rebound, they will continue to take short positions to cut losses, and the price will slowly rise, then close the door. 2. If the price drops too much, the rebound will be very strong. Mathematically speaking, it is unfair to the Air Force. If the price drops by 50% and rebounds to the original price, it will be 100%. This is the inherent disadvantage of the Air Force
