Hello Blinky,

Thank you for your post.

First please reset your instruments with 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

Next use the steps I have provided below to add the instrument to your list:

• Go to Tools->Instrument Lists
• Select your list on the left
• Click add within the right panel
• Select ES
• Click Enter
• Click Ok

Let me know if I may be of further assistance.
