There is nothing wrong with this! See which price you think is unreasonable. Of course, if you want to hold a position for a long time, you can't speculate on the current contract. In addition, upstairs said that the current contract is generally based on liquidation on the final delivery date. However, it does not rule out that sometimes the current contract is far from the average value of the 300 index in the morning. Then buying or selling the current contract at this time may have greater gains before the final closing of the contract in the afternoon. And relatively safe. So it depends on the specific situation.
