The customer himself can't inquire about the trading authority, but can only consult the futures company and inquire through the futures company. But when opening an account, the customer can choose the exchange and variety of the account, so the customer usually knows his trading authority. For example, if a customer doesn't open a CIC, that is, he doesn't have the right to trade fixed stock index futures, then he certainly doesn't have the trading right of CIC. There are also special varieties of trading authority, such as crude oil, iron ore, PTA and so on. If it is not opened, there is naturally no trading authority. In fact, the simplest way to query is to directly log in to the account and choose to trade this variety, and the system will prompt whether there is trading permission for this variety.
