Connect to IB historical minute data failed

[Benluk]

At the end of each trading day, I used to update Ninjatrader charts from IB. Yesterday and today I encountered an error message and the loading stopped.

Error on loading chart data for ÝM 06-15 Glodex': Interactive Broers:
Error in requesting historical data from IB. No security definition has been found for the request(200)

On IB platform, the symbol is spelled as YM Jun 19'15 @ECBOT.
On Ninjatrader, the symbol from Instrument Manager is YM 06-15 and the exchange is Globex, Expiry is 06-15.

I think I did the same in the last few years. Not sure why it does not work this time. Any suggestions?

Hello,
Thank you for your post.
Can you verify if you are receiving the data for the YM 06-15 in Traders Workstation?
Does this error appear on a new YM 06-15 chart?
Does the error message persist after resetting your instruments?
To reset your instruments please:
Disconnect from all Data providers, go to the Tools menu, select the Options menu item, select the Data tab, and then click on 'Reset Instruments' and restart NinjaTrader.
I look forward to your reply.

IB received data for YM 06-15.

The error message happens on the new chart YM 06-15. But it worked a few days back when I started rollover. It failed yesterday and today.

I follow your resettling procedures, looks like the data comes back as normal now.

Could you explain what went wrong? What does reset instrument mean?

Hello,
Resetting the instruments resets the symbol mapping for all of the preconfigured instruments.
This indicates that the symbol mapping for the YM was incorrect.
If we can be of any other assistance please let us know.

Connect to IB failed again

It worked yesterday. It failed today again.

Please see the threads. Everything is the same. Get the same error.

I repeat the reset instrument process. It does not help this time.
