Lists of tradeable objects may be generated and displayed to enable a user to define a trading strategy having multiple legs. The lists of tradeable objects may be used to define and display different combinations of the tradeable objects that are included in each of the lists. Each combination of tradeable objects may define the different legs of a spread that may be tradeable on one or more exchanges. A combination of tradeable objects may be selected to display contract information associated with the different legs of the spread. The contract information for each leg may be used to define and display spread information for the legs of the trading strategy. The spread information may allow the user to view information related to the spreads for different combinations of tradeable objects in a display.
