Volatility Calculator Overview
The Volatility Calculator widget is used for calculating the Theoretical Value and Implied Volatility of an option at any underlying price. You can enter a Theoretical Value of an option to calculate its Implied Vol, or enter the option's Implied Vol to calculate its theoretical option price.
