Currently, the daily rebound has reached the support level. This is the second time reaching this position, and it is highly likely to break directly. If this support can have a strong rebound, it can be shorted again at a high level. So the current strategy is to short at the high each time to earn profits, and to decisively take profits and lock in gains. I started with a mid-to-long-term short position at 82,000, gradually taking partial profits each time a bottom of the decline appears. I favor mid-to-long-term shorts. Why do I keep taking profits?
