I saw someone else's screenshot and asked this question. I also want to ask how to breakeven in this situation. Is there a specific method of operation? Is closing the position feasible? Please comment on this answer. I don't understand.

Plan: First, add margin to the short position to protect the long position from liquidation, then close the long position. After that, the price should be around 3100-3200, and then select a position to increase the position size, pushing the average opening price close to 3500. It will breakeven within a week.
Remember: Do not close positions with one click, and do not enter a single position without any preparation; both practices will only lead to liquidation, which your current positions cannot bear. Additionally, after breakeven on one position according to the plan, it's best not to add positions if possible. Choose to retain positions as a reference, and engage in reverse-direction ultra-short trades with high leverage for quick entry and exit. The price will soon be gradually pushed to your breakeven point.
