.BXBTT30M Index Details
The BitMEX .BXBTT30M Index is a 30-minute TWAP of the Bitcoin price from the .BXBTT Index. These values are used for settlements. The TWAP is calculated every 4 hours.
This index is composite, which means the price is built from multiple sources. See the "Composite Index Breakdown" below for information on the constituents. If an exchange is to lose service and no trades are printed for over 15 minutes, BitMEX services may automatically remove that constituent from the index until trading resumes.
