This page describes CVOL Intraday Values data available from CME DataMine.

The CVOL Intraday Values files contain the aggregated intraday tick-data for CVOL indices and are compiled on an end of day basis allowing users to consume and store the intra-day index levels of the Live Streaming CVOL.   

The Live Streaming CVOLs are derived from the world’s most actively traded options on futures contracts across major asset classes and are calculated every 15 seconds (during the calculation windows) for the respective Live Streaming CVOL together with the associated derivative indicators. The Live Streaming CVOLs deliver the first-ever cross-asset class family of implied volatility indexes based on simple variance. Using our proprietary simple variance methodology that assigns equal weighting to strikes across the entire implied volatility curve, the the Live Streaming CVOL produces a more representative measure of the market’s expectation of 30-day forward risk, calculated every 15 seconds.
