Volatility Page Layout
You can apply a volatility page layout that lets you create option orders based on volatility instead of price.
To use the Volatility layout for an existing page
On the Page menu select Settings.
In the Layout drop-down, select Volatility and click OK.
When you apply the Volatility layout, the Bid Price and Ask Price fields for options market data display volatility instead of price, illustrated by a percent sign (%) after the price. The first time you open the Volatility page layout, you will see several volatility columns to allow you to trade Volatility, including Order Volatility, Volatility Type, Stock Range (Low), Stock Range (High), Hedge Delta Order Type, Hedge Delta Aux. Price, Continuous Update, and Reference Price Type.
NOTE: If you have options listed on the same trading page as stocks, when you switch to Volatility layout you will see the bid/ask prices for your equity contracts.
