From February 17th to February 18th, the position was just closed. The fluctuations of the two lines were too big. I almost lost the cabin. Fortunately, I pulled it back. The overall market is still relatively strong for the long side, and the short side of the market is weak. Personally speaking, The market for the recent correction will fluctuate between 49,000-50,000! Make direction judgment again based on the chips on the board! Profit in these two days +605
