1. The futures exchange is the place to buy and sell futures contracts and the core of the futures market. It is a non-profit organization, but its non-profit only means that the exchange itself does not conduct trading activities and is not for profit, which does not mean that it does not talk about interest accounting. In this sense, the exchange is also a financially independent profit-making organization. On the basis of providing traders with an open, fair and just trading place and effective supervision services, we will realize reasonable economic benefits, including membership fee income, transaction fee income, information service income and so on. A set of institutional rules formulated by it provides a self-management mechanism for the whole futures market, thus realizing the principle of "openness, fairness and justice" in futures trading.

2. The futures market is a financial market that trades according to the agreement reached and delivers on the scheduled date. The obvious difference between spot and futures is that the delivery date of futures is the future, and the terms of delivery and payment such as price, quantity, method and place are agreed by the buyer and the seller in the spot contract. Commodities and securities can be traded in the futures market. Although the contract has been signed, the goods bought and sold by both parties may be in transit, in production or even not put into production. The seller may or may not have goods or securities in hand.
