The mistake made earlier was that since I judged there was accumulation and a shakeout happening, I should have added a long position near 2590. On one hand, the selling pressure wasn't significant, and on the other hand, there was a second pin probing the bottom at 2588.
This highlights the gap between my analysis and that of strong KOLs, who either anticipated or captured this opportunity.
I need to continue improving my trading methods and enhance my sensitivity.
