At the beginning, the position of 2669 was about 40 points away from 2630, and then our defensive position was very extreme.

The first time was at 2646, and the second time was at 2638. If it were not for rational analysis, I would seriously suspect that I was being targeted by the dog brother.

The price did not change, but the space was gone. Although it was still profitable overall, the profit was really greatly reduced, and some friends who could not help but do 🈳 were completely numb.

So through this demon, we also know our shortcomings, so we still need to optimize and improve some details in the future
