Before 9:30, it is call auction time, so we can entrust it, but we won't know if we can close the deal until the opening price comes out at 9:25.

Note, however, that orders can be cancelled during 9: 15-9: 20, but not during 9: 20-9: 25. Many main players like to intentionally put up orders at 9: 15-9: 20 to push up the price, and then cancel the orders before 9: 20 to attract small companies to put up high-priced orders to achieve their high-priced sales. During 9:20-9:25, there were many consignments and the prices changed rapidly. It is best to sell the stock after 9: 24, and it is best to trade it at a price a few cents lower than that of call auction at that time. If you buy it, you'd better sell it at a price a few cents higher than that of call auction at that time.
