The handling fee of stock index futures includes 0.25 yuan of the exchange and part of the futures company. Futures companies charge different service fees to each company's customers. Please consult the futures company or your broker for details. The return of the exchange to the futures company is not fixed, and sometimes a part will be returned to the futures company for several months every year. The main reason is that the fee competition is too fierce now, and many futures companies don't make money. In order to make futures companies have enthusiasm, futures companies make a symbolic return point. After all, the big head is still earned by the state.
