As of 19 March at 04:00 UTC, the Mark Method for ETHFIUSDTH24 was changed to Fair Price marking.
This was possible, as we have now constructed a robust index that represents the spot prices of ETHFI.
ETHFI is now priced on the .BETHFIT index which incorporates ETHFI prices from Binance, OKX and Gate.io.
Please note that this also means Limit Down and Limit Up price protections have been removed.
