What is the selection method of stock quotation at market price?

1, limit order: the specified price. If it is a purchase, it will help you buy at a limited price or lower. If sold, it will help to sell at a limited price or higher. 2. Counterparty optimal price entrustment: the declared price is the optimal price of the counterparty queue in the centralized declaration book when the declaration enters the trading host. As far as the implementation effect of the declaration is concerned, the declaration of the counterparty's optimal price is equivalent to the limit declaration of the real-time market "buy one" price as the selling price or the real-time market "sell one" price as the buying price without considering the difference of market information. The declared price is the optimal price of the counterparty queue in the centralized declaration book when the declaration enters the trading host. 3. Our best price declaration: the declared price is the best price that we queue up in the centralized declaration book when the declaration enters the trading host. 4. Withdrawal of the remaining orders of the fifth-grade instant trading: when the number of shares entrusted to buy or sell exceeds the number of open shares in the current displayed price of the fifth grade, the open shares will be automatically withdrawn after the transaction is completed according to the existing number of shares in the fifth grade. For example, if you want to buy 20,000 lots, there are only 15000 lots in the fifth gear at present, and the remaining 5000 lots will be automatically cancelled after 15000 lots are sold.
