Double opening of futures is a term in futures trading, which is used to express the nature of futures trading. Double opening of futures refers to buying and selling the same product at the same price without knowing whether the futures market is going up or down. Buying and selling together is a transaction. In the process of transaction, the quantity bought is equal to the quantity sold.

For example, investor A wants to buy 10 wheat contract, and investor B wants to sell 10 wheat contract, so both of them open positions at the same time (B transports the contract out of the warehouse and A transports the contract into the warehouse), and the transaction can be successfully completed.
