To further strengthen the trading of our XBT/USD products, BitMEX is proud to announce the introduction of Kraken’s XBT/USD price feed into the BitMEX .BXBT Index. This will bring the number of constituents in our primary index from 2 to 3.
This change will take place on Sunday, 16 September 2018 at 12:00 UTC on our XBTUSD Perpetual Swap product, new Futures products and on our Option products. Existing XBT/USD futures products that have not settled will remain under the existing index.
New Index Composition
.BXBT, the BitMEX XBT/USD Price Index, will change from (½ * Bitstamp + ½ * Coinbase Pro) to (⅓ * Bitstamp + ⅓ * Coinbase Pro + ⅓ * Kraken).
Interim Index for Existing Futures Listings
.XBT is identical to the old .BXBT index: (½ * Bitstamp +½ * Coinbase Pro). This index will only be used for in-progress futures as not to modify their composition mid-contract.
This new index will be phased out after the settlement of the affected products (28 Dec 2018 12:00 UTC).
