IV Rank normalizes implied volatility into a 0–100 score that tells you where current IV sits inside its own 52-week range. It is the cleanest way to decide whether option premium is rich or cheap on a specific underlying — far more useful than the raw IV number, which means nothing without context.

    IV Rank

    IV Rank normalizes implied volatility into a 0–100 score that tells you where current IV sits inside its own 52-week range. It is the cleanest way to decide whether option premium is rich or cheap on a specific underlying — far more useful than the raw IV number, which means nothing without context.

    Quick definition

    Implied Volatility Rank measures where current implied volatility stands relative to its range over the past year. An IV Rank of 80 means current IV is higher than 80% of readings in the past year.

    How it is computed

    IV Rank = (current IV − 52-week low IV) ÷ (52-week high IV − 52-week low IV) × 100. A reading of 80 means current IV is higher than 80% of the prior year's readings — premium is historically expensive, favoring credit (premium-selling) strategies. A reading of 20 favors debit (premium-buying) strategies.

    Why traders prefer it to IV Percentile

    IV Percentile counts how many days IV was below today's level. IV Rank uses the high–low band. Rank reacts faster after volatility regime changes because it doesn't need a full year of dates to recalibrate — one new high or low instantly shifts the denominator.

    How Treeova uses it

    Several built-in agent archetypes — wheel, iron condor, jade lizard — gate entries on IV Rank thresholds because their edge comes from selling rich premium. Conviction Scoring also folds IV Rank into the volatility lens of Arch-AGI so a high-IV-Rank setup contributes positively to a credit agent's conviction and negatively to a long-premium agent's.
