Futures trade future commodities, and contracts are time-limited, which is the binding force and legitimacy of commodities. Your transaction itself is still a commodity, and the contract is only his form and execution certificate.

If you are a legal person account, if the contract you hold has expired and has not been closed, then the buyer will go to the exchange to complete the corresponding procedures for paying the bill and the seller will complete the corresponding procedures for selling the bill.

Of course, if you are a natural person account, the exchange will force you to close your account before the delivery month.

Therefore, the price does not point to the contract itself, but to the object of the contract-the commodity.
