Understanding IV Metrics

Implied volatility is how much price fluctuation the market expects, derived from option prices. High IV means expensive options; low IV means cheap ones.

IV Rank

IV Rank shows where the current IV falls within the 52-week high-low range. An IV Rank of 0% means IV is at its lowest point in a year; 100% means it's at the highest.

IV Percentile

IV Percentile shows what percentage of trading days in the past year had lower IV than today. 80% means today's IV is higher than 80% of days in the past year. Unlike IV Rank (position in range), IV Percentile tells you how rare the current level is.

30-Day IV

30-day IV is calculated by averaging the implied volatilities of at-the-money call and put options, then interpolating between the two expirations that bracket 30 days to estimate a constant 30-day IV. Data updates daily after market close.
