For most contracts, we allow trading in the front month contract as well as the next active back month. For certain products, we allow additional back months to be traded. To request additional back months be enabled for your account, please submit a Risk Change request including the details of what products you’d like to trade as well as the number of contract months you’d wish to trade in.
To request a Risk Change, navigate to Application Settings.
Then from the Accounts tab, click the Risk Settings button for the account you wish to manage.
In the details section choose Request a Custom Risk Setting.
