1. First of all, the exchange will close the positions of customers who are not qualified for delivery (such as individual customers and customers who need to issue VAT invoices for certain transactions), even after the closing of the last trading day.

2. If there are still positions that can't be closed (because there are still rival orders that can't be closed), then the exchange will force you to implement the delivery procedure of the buyer's position. If the delivery procedures are not fulfilled (such as insufficient funds, because only 50% of the deposit is needed before the last trading day), the exchange will usually impose a fine of 15-30% of the total value of the delivered subject matter.

For the seller's position, if the delivery procedures cannot be fulfilled (no goods can be delivered), the exchange will buy the goods that meet the delivery standards in the spot market and pay them to the corresponding buyers. The difference between the price difference and the delivery price will be borne by the defaulting seller, and the seller will be fined 15-30%.
