One of the more useful data points our scanner has is the IV rank. Unlike other columns this is one of our default columns.
What is IV rank?
We use implied volatility rank a bit different from what you might used to and apply IV percentile to calculate it: it is a measure of implied volatility vs its past values.
Reading the table
The figure represents the percentage of past values that the current IV value exceeds.
- The top value is the the IV Rank that we calculate and its color is determined by its change: Green - increase; White - Neutral; Red - Decrease.
- The bottom figure is the stock’s IV value that is calculated.
