Adding Instrument

[JerryA]

How do I add UB June 18? I tried the Rollover method - everything is still in March. Message was "there are no rollovers for these contracts" or something like that.
It used to be able to add a new contract very easily. Everything in NT8 is such a hassle - if it ain't broke, don't fix it.

Hello JerryA,
Please follow these steps to roll over the expiration date of a Futures contract:

Navigate to the Control Center > Tools > Database window.
Left-click the ‘Rollover’ button that appears just below the table under the ‘Rollover futures instruments’ section.
Close this window when this process completes.

As I mentioned in my original post, the Rollover didn't work - 2 symbols are the current contract and the others are still March. So once again, how do I add UB June?

Hello JerryA,
Can you please reset your instruments and perform the rollover again?

To reset your instruments, please take the steps below.

First, disconnect from any data providers by navigating to the Control Center > Connections menu, and left-click on “disconnect” that appears to the right when hovering your mouse over any active connection
Next, reset your instruments by navigating to the Control Center > Tools > Database Management
In the Database Management window, under the “Update instruments” section, ensure that “General properties”, "Futures expiries" and “Symbol mappings” options are checked and then click Update
Lastly, restart NinjaTrader for the changes to occur
