When I was in call auction, I didn't see the turnover, but there was turnover. The first list is usually showing thousands of lots. When you open it for the first time, you will know that it will appear at the first time.

The market opening of call auction futures should be conducted within 5 minutes before the market opening of a certain variety of contracts in a certain month, in which the first 4 minutes are the declaration time of futures contract orders, and the next 1 minute is the call auction matching time.

Generally, it should be able to report to the exchange before 8: 59. Maybe your network (or Northern Futures) is slow, or the computer time is inaccurate, so you missed the time in call auction. You can report it earlier in the future.
