Friday sold at 59k, recovered to 64k on Sunday, and yesterday it returned to 61k.

This is not a single misjudgment. It’s three times. First panic selling at the needle’s eye, then FOMO chasing at the rebound top, and then being worn down by three days of downward decline.
Between 59 and 64, the direction was unclear. Every order within this range was not about predicting the right direction, but betting that my luck this time would be better than last time.
I didn’t make any moves this Monday, continuing to hold my short position. If 59k can hold for two more days without making a new low, I will consider buying some long positions here. The problem is that almost every planned rebound this week has failed to hold support.
So, there’s no way to confirm a rebound; I expect it will first fluctuate for a while, but the current range of fluctuation can’t be confirmed yet.
