As of 21 November at 10:00 UTC, the Mark Method for PYTHUSDTZ23 was changed to Fair Price marking. This was possible, as we have now constructed a robust index that represents the spot prices of PYTH. PYTH is now priced on the .BPYTHT index which incorporates PYTH prices from Bybit, OKX, Kucoin, and Gate. Please note that this also means that Limit Down and Limit Up price protections have been removed. If you have any questions please contact Support.
