How far the market EXPECTS price to move, priced off options (the DVOL index). Every other derivatives tool here describes how the market is POSITIONED; this one prices how expensive protection is. Returns the current 30-day implied volatility, annualized, in PERCENT (34.95 means 34.95%), together with its min, median, max and PERCENTILE over the window — an IV of 35% says nothing alone, but at the 5th percentile of the last month it says optionality is cheap and the market is complacent. Also returns the derived expected move (plus or minus percent over 1, 7 and 30 days), which scales with the square root of time, not linearly: dividing annualized IV by 365 instead of by the root understates a one-day move roughly nineteenfold. Distinct from the VIX reported by get_macro_rates, which is US equity volatility, not crypto. Published for BTC and ETH only; any other coin comes back under "unavailable" rather than failing the request.
