Proprietary business refers to the behavior of futures companies to conduct futures trading with their own funds.

Before 1999, futures companies were allowed to carry out self-operated business, but after the implementation of the Interim Regulations on the Administration of Futures Trading, self-operated business was prohibited and they could only do brokerage business (agency business) for customers.

Members who are not futures companies can only engage in self-management, not brokerage business.
