My plate is open, and there is nothing left. The following are the functions of futures:

1. Network problem: Please check whether your network connection is normal, and try to reconnect the network or change the network environment.

2. System problem: The system may be abnormal. Please try reopening the futures trading board or restarting the equipment.

3. Server problem: If you still can't open the futures trading section after many attempts, it may be that the server is out of order or maintenance, please contact the relevant customer service or technical personnel for handling.
