CBOE Global Markets, Inc. has launched its new index on bitcoin futures, the Chicago-based derivatives exchange announced on Wednesday.

Following the launch of its bitcoin futures contracts earlier this week, the CBOE has created a new index designed to replicate a constant one-month position in CBOE XBTSM bitcoin futures, the CBOE Gemini bitcoin futures index.

The new strategy performance index, “is designed to track the performance of a systematic strategy that holds a long position in XBT futures that is rolled continuously throughout the period between the futures last trade dates to maintain a constant one-month XBT futures exposure,” CBOE says in a statement.

CBOE will begin disseminating the index through quote vendors on Dec. 14.

More than 5,000 of its bitcoin futures contracts have been traded so far, the exchange says.
