From 9: 25 to 9: 30, you can't hang the bill or cancel it. After 9: 25, the system matches transactions according to the principle of time priority and price priority, but the order is temporarily stored in the brokerage system and then submitted to the exchange at 9: 30. The purpose of setting up call auction is to prevent the stock price from being manipulated artificially, because the number of buyers and sellers can't be seen when assembling.
