What is an 8-Hour session settlement mechanism?

MoonXBT USDT perpetual contracts adopt a settlement mechanism every 8 hours to settle the unrealized profit and loss in the position into realized profit and loss, which is reflected in the cash balance account to improve the utilization rate of your assets. 

For example, if the position held at the time of settlement has a profit of 200 USDT, it’s credited to the cash balance.

Settlement occurs every 8 hours at 08:00 UTC, 16:00 UTC, and 00:00 UTC.
