There are two bidding methods for futures trading, namely call auction and continuous bidding. Among them, call auction adopts the principle of maximum delivery five minutes before the opening of futures, and finally produces the opening price of the day, which is called call auction time.

After the bid opening, continuous bidding will be adopted. The so-called "continuous" means that the process of bidding and closing is uninterrupted. During the trading time, the buyer and the seller make their own trading declarations, and then they begin to enter the stage of matching transactions. The computer trading system sorts the trading declarations according to the principle of price priority and time priority, and automatically matches the transaction.

This is a matchmaking deal. Generally speaking, follow the principle of price priority and time priority. When the daily limit is up and down, follow the principle of liquidation priority and time priority.
