Change of Mark Method for ARBUSDTM23

On 18 April 2023 at 04:00 UTC, we will change the Mark Method for ARBUSDTM23 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 ARB – the .BARBT index – which incorporates the ARB prices from Binance, Bybit,, Huobi, Kraken 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.
