How long can futures be successfully traded after liquidation?
The transaction time is based on the server time obtained from the transaction, not the time on our computer. There is indeed a gap of several seconds between the time on the exchange server and the time on our computer. When you see that your computer time is 3 o'clock, in fact, the exchange server still has a few seconds before 3 o'clock, so you can still have a few seconds to make a transaction after 3 o'clock.
