Transaction records refer to the written records of relevant information about the conclusion of transactions in futures exchanges. Futures trading records need to record not only the name, month, price and quantity of the trading contract, but also the numbers of the counterparty's brokers and their settlement members, while the names of customers who originally entrusted brokers to place orders need not be registered. Once the transaction record is completed, the broker and the floor runner will quickly send it to the clearing house, which will check it and confirm the profit and loss results after the transaction.
