The difference between account crude oil products and account crude oil continuous products: 1. Different trading methods: the crude oil products in the account are issued in installments, and the trading start date, trading end date and settlement date are set for each installment. You can buy and sell this product during the trading hours from the trading start date to the trading end date. After the product expires, except for the products that have been reserved for extension, it will not be possible to continue trading. Account crude oil continuous products can be traded continuously. There is no transaction end date, and there is no need to set a product extension date. The crude oil continuous products in your account will be automatically adjusted by the system after the transaction on the share adjustment date, and the total assets will remain unchanged before and after the share adjustment. 2. The naming rules are different: the product names by stages adopt the combination of "transaction currency+transaction variety+reference contract code". Continuous trading products are named after the combination of "transaction currency+transaction variety".
