3.5.2 Historical and Implied IV Gauges

The HV and IV gauges are quick looks at the underlying’s volatility over a certain period. From left to right we can see how the market maker is pricing in the implied volatility of the underlying in 10,30,60, and 90 days. In the same order for the historic volatility, we can see what the underlying’s historical 10,30,60, and 90 day volatility has been. There is no standard “Is 90 a high IV?” because it depends on the stock, the historic volatility, and what that stock’s IV level is currently at.
