IB was unable to locate verify your symbol mapping'' issue on some NQ/YM contracts

[Murphy67]

When I am installing chart I am getting ''verify your symbol mapping error. on some contracts.
When running strategy on NQ, no issue from 03-18 to 03-19 ( 8 contracts), but getting error on 03-20,06-20 and 12-20, rest contracts including 09-20 no problem.
On YM only problem on 09-18, all others from 03-18 till today no problem.
ES doent have any issue

Why having problem on some contracts, and others not.

How can i fix it?

IB gateway connection 10.19
NT8 8.027

Hello Murphy67,

Thank you for the message.

Please begin by updating/resetting the instruments within your platform:

1. 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
2. Next, reset your instruments by navigating to the Control Center > Tools > Database Management
3. 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
4. Lastly, restart NinjaTrader for the changes to occur

After restarting NinjaTrader, reconnect to your account and test if the charts load in.

If the behavior continues, do the messages appear when you try to create the chart? Or, do the messages not appear until you try running your strategy?

Please let us know if we may provide any further assistance.

Hello Murphy67,

Thank you for the message.

If you changed the Trading Hours template on a chart or window, you would want to save the Workspace after doing so to save the changes in there.

• Right-click on the chart > Select Data Series
• Under Properties > Time frame > Trading Hours, Select your desired Trading Hours Template > Click OK
• Go to the Control Center > Workspaces > Hover over the workspace with a green icon next to it > Click save

The Next time you reopen NinjaTrader, it should have the same Trading Hours template selected within that Chart window.

Please let us know if we may provide any further assistance.
