On 18 January 2023 at 04:00 UTC, we will change the Mark Method for FLRUSDTH23 from Last Price to Fair Price. We are able to do this because we have now constructed a robust index that represents the spot price of FLR – the .BFLR and .BFLRT index – which incorporate the FLR prices from Gate.io, Kraken, Kucoin, and OKX. Please note that this will also mean the removal of Limit Down and Limit Up price protections. Fees will be updated so that maker and taker fees align with our standard fees. If you have any questions please contact Support.
