Is Your Ticker's Volatility Rich, or Cheap?
IV Rank measures where a ticker's 30-day implied volatility sits in its one-year range, from 0 (the cheapest it's been) to 100 (the richest). The IV Rank tool finds every past day at a similar rank and shows you what price did next.
A raw IV number tells you almost nothing on its own. Is 35% implied volatility high? For a sleepy index, very. For a meme stock mid-squeeze, it might be the calmest the options have been all year. The only way to read IV is against the ticker's own history, and that is exactly what IV Rank does: it places today's 30-day IV on a 0 to 100 scale, where 0 is the lowest it has been over the past year and 100 is the highest.
Knowing the rank is half the job. The other half is conditional: my ticker's IV Rank is up here (or down there), what has price historically done from a reading like this? Rich volatility and cheap volatility set up very different trades, and the forward distribution is the part most traders never actually measure.
A live IV Rank read, a 45-day forward price cone, a Chance of Move bar graph, a full sortable event log, and a watchlist scan of where rank sits across the board.
One glance tells you where today's implied volatility sits in its one-year range, from 0 to 100.
Projects the next 45 days by applying forward returns from past days at a similar IV rank.
How often price rose or fell by a set percentage after similar IV-rank readings.
IV Rank places today's 30-day implied volatility in its one-year range: 0 is the cheapest it has been, 100 the richest.
The tool scans the market and auto-highlights stocks at the richest and cheapest IV ranks today.
The Historical Log displays every past instance at a similar IV rank to today's.
Check if any stocks on your watchlist or in the market are at a rich or cheap IV rank today.
Open the 45-day price cone. It shows how price behaved after similar IV-rank readings in the past. This gives you a realistic view of what typically happens next instead of guessing.
Switch to Bar Graph view and set your target price level. The bars show how often similar IV-rank readings reached that distance by upcoming expirations. Toggle between "By Touch" and "By Close" depending on your strategy.
Before acting on the signal, open the events log. Check how many historical matches exist and whether they cluster in one period. A small sample or regime-specific cluster tells you the signal may be less reliable than the percentages suggest.
