Shanghai, Dalian and Zhengzhou commodity futures exchanges and China Financial Exchange (stock index futures) have 22 listed varieties, and different varieties charge different fees. All futures companies are members of exchanges (financial exchanges are not). A fixed part of the customer's fees for participating in futures trading will be paid to the exchange, and the other part will be collected by the futures company. The standard for charging futures companies is to add a part to the futures exchange for its own operation. Different futures companies charge different fees in different regions. Relatively large and powerful futures companies charge higher fees, while some small futures companies charge slightly lower fees. The handling fee will also vary according to the customer's capital size and transaction volume. For customers with a large amount of funds or even millions, futures companies will also moderately reduce the handling fee.
