What is IV Rank?

IV Rank measures where the current implied volatility sits relative to its range over a lookback period (commonly 52 weeks). It is calculated as ((Current IV − IV Low) / (IV High − IV Low)) × 100. A higher IV Rank suggests options are relatively expensive; a lower IV Rank suggests they are relatively cheap.
