Further information on the composition, calculation and scheduling of BitMEX indices is available.
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.
The BitMEX index weights are computed using volume data obtained directly via API connection from each of the constituent exchanges listed above. Proprietary mechanisms are used to identify malformed and anomalous data, which is discarded. The index weight calculation removes constituents with insufficient trade volume.
For the avoidance of doubt, and in accordance with BitMEX Terms of Service, HDR Global Trading Limited (operator of the BitMEX trading platform) accepts no responsibility for the accuracy of any volume (or other) data received from any exchange and used to calculate the value of any BitMEX index and excludes all liability for any claimed losses arising in connection with its calculation and publication of any such index.
