Will be closed (or forced to close). According to relevant information, the essence of futures is to sign a sales contract. Individual customers are not allowed to make physical delivery, so they should close their positions (or force them to close their positions) before the contract enters the delivery month. The positions of corporate customers will gradually increase (to 30% of the contract value). Failure to deliver the expired contract is regarded as breach of contract, and the exchange will deal with the customer.
