TradeStation Help
The OptionStation Analysis toolbar appears when the OptionStation Analysis window is active. It provides access to many window commands and formatting features, including the ability to control the selection of expiration and strike values for spreads.
The spread option chain settings allows you to select the type of spread and various parameters used to display the spread in the OptionStation Analysis window. The Strike Proximity and Expiration Date Proximity settings determine how many option Puts and Calls are displayed in the options pane.
Use Spread View to select the name of the spread option chain to display in the spread pane of OptionStation Analysis window. The Strike Spread setting is used to specify the number of strikes prices above and below the price of the underlying asset and the Expiration Spread specifies the number of Expiration Dates to include in the spread.
