As of 22 February at 07:15 UTC, the Mark Method for PORTALUSDTH24 was changed to Fair Price marking.
This was possible, as we have now constructed a robust index that represents the spot prices of PORTAL.
PORTAL is now priced on the .BPORTALT index which incorporates PORTAL prices from Binance, Bybit and Gate.io.
Please note that this also means Limit Down and Limit Up price protections have been removed.
