You read it correctly. 1 107 refers to the contract that expires in July. If it is an enterprise, it can hold it until the last trading day, prepare the money or send the goods to the delivery warehouse, and do a good job in inspection and warehouse receipt registration. If you are self-employed, you cannot enter the delivery month, and the exchange does not allow individual traders to enter the delivery month. In other words, the contracts held by individual households must be closed before July, otherwise, the exchange will give compulsory closing on the first trading day of the trading month.
