How do I choose the correct account to trade?

If you have two or more accounts tied to your DAS user, like your live account and a training account (TRxxxx), you can choose which account to use in the dropdown in the montage. You can also setup a default account: Setup>Order Template> Account> “Apply this Setting to All Exchanges”>Apply. Then go back to the montage and left click on your “TMP” button to load the settings.
