For any exchange traded commodity for which there are exchange prices available, you can see this data in the Exchange Prices window.
In this window, the expiry date of the option contract is displayed next to each option contract's name.
To access this window:
From the ribbon bar > Market Data tab click the Exchange Data button.
From the ribbon bar in any tab click the Open button (to open the System Menu) and then click Exchange Prices.
From the pricing page by clicking the Exchange Prices tab on the left hand side of the window.
By opening the commodity’s Term Structure.
In this case, you only see the Exchange Prices window if you have configured the Term Structure to open in the Exchange Prices display mode. You do this in the Customize window > Term Structure tab > Display Mode dropdown list.
In the Exchange Prices window, you can also choose to display the SD prices for the same commodity so you can compare them. You do this by clicking the Add SD Prices button. Note, however, that this button is only displayed if you have enabled it. You do this in the Customize window > Term Structure tab by checking the Display SD Prices Button checkbox.
