DVOL
Deribit's 30-day implied volatility index for Bitcoin, the crypto analogue of the VIX.
DVOL is Deribit's implied volatility index: the market's 30 day forward expectation of how much Bitcoin will move, expressed in annualized percent and derived from the option chain. It is the closest crypto has to the VIX. A rising DVOL means options are getting more expensive because the market expects a wider range, which can happen into either a rally or a selloff, so it measures expected movement rather than direction. Like every volatility index it is most useful as a percentile against its own history rather than as a level, and it mean-reverts: extreme readings in both directions have historically not persisted. We hold the daily series back to 2021-03-24, which is 3,932 days of history at the time of writing.
