how do i delete/replace a data series in the default list

[joemiller]

My futures chart needs to be rolled over from September to December expiration. Please tell me how to delete the old month from the default list of data series and to add the new replacement month ... or otherwise do a roll over?

Hello joemiller,

Please follow the instructions below to rollover the expiration date of a futures contracts.

From within the NinjaTrader Control Center window select the menu Tools > Instrument Manager
Highlight the contract you wish to rollover in the left side of the Instrument Manager window
Press the ">" button (the instrument will disappear from the list)
Press the "<" button and the instrument should re-appear with the front month expiration date
