Buyers and sellers of futures contracts do not need high trust. Don't trust anyone in the future, including yourself. It is very difficult to trust and strictly abide by a good trading system. In reality, due to various disappointments in actual transactions, it will always become difficult to implement. A futures contract is an agreement in which the buyer agrees to receive assets at a specific price after a specified time, and the seller agrees to deliver assets at a specific price after a specified time. The price that both parties agree to use in future transactions is called futures price. The designated date on which both parties must conduct transactions in the future is called settlement date or delivery date. The assets that both parties agree to exchange are called the subject matter.
