Please note that from Tuesday 26 September 2023, in low liquidity conditions, PnL realisation for some contracts will be auto-disabled from 04:00 UTC.
This will happen whenever the distance between the impact bid or the impact ask, and the mark price is greater than the maintenance requirement for a contract, or if an impact bid or impact ask cannot be calculated.
You can find the current state by contract and instrument tables here.
These changes are to protect the integrity of the exchange and ensure a stable trading environment for all BitMEX traders. They are subject to change at any time, with short, to no notice.
