OptionStation Pro
The Option Chains panel enables you to see all the CALLS (on the left) and PUTS (on the right) available for the expiration term you have opened.
At the top of the Option Chains panel is a Spread Type drop-down menu that lists several standard spreads. Clicking on any one of these spread types will update the Option Chains panel to show the available options in the form of the selected spread.
For example, selecting a spread type of Butterfly would display an option chain that includes three Butterfly strike prices in the Strike column.
Full customization of the spread for changing strikes, number of contracts, and other criteria are available in the Theoretical Positions panel.
Using the Option Chains panel to view options based on a particular spread allows you to see the total premium for the spread (Bid, Ask, or Mid prices), the composite Greeks and volatility values, as well as your positions.
To enter a Theoretical Position to analyze, click on the Bid or Ask price for the option or spread you are interested in. Click the Bid of the option or spread to create a Short position. Click the Ask to create a Long position. Click on the left side of the Strike column to use Calls. Click the right side of the Strike column to use Puts.
When a Theoretical Position is created, it will be placed in the Theoretical Positions panel.
