As of 19 Dec 2024 at 09:00 UTC, the Mark Method for USUALUSDTZ25 was changed to Fair Price marking.
This was possible, as we have now constructed a robust index that represents the spot prices of USUAL.
USUAL is now priced on the .BUSUALT index which incorporates USUAL prices from Binance, Kucoin, and Bitget.
Please note that this also means Limit Down and Limit Up price protections have been removed.
