Log: Symbol Mapping

[Murphy67]

Hello,
After reinstallning Nt8, i tried to pull the data from TWS and run strategy analyzer last week. But results were wrong because of some datas were missing.
Then, i connected Kinetick with TWS (multiple connection), and choosed prefered connection Kinetickfor historical tradeand ,and live data from TWS.
And, Strategy analyzer worked fine, issue solved.
But, now, whenever TWS loss connection and connect again, Log files messages are ''IB was unable to locate instrument Pls verify your symbol mapping''. for some contracts.

Current setting merge non back adjusted, as said all historical datas works well. i just getting these errors.

Hello Murphy,

Thank you for your post.

I would first like to ensure that you are using the fully supported version of Trader Workstation (981.3i) as outlined in your Interactive Brokers Connection Guide Below:

• https://ninjatrader.com/ConnectionGu...nnection-Guide

You may find the version you are using by going to Help > About within Trader Workstation.

If you are not using these listed version then I would recommend uninstalling the current version you are using and then using the download links in the Connection Guide above to install the supported versions.

Hello Murphy67,

Thank you for your note.

These would be expected as these are expired Futures Contracts and Interactive Brokers does not supply data for these instruments due to being expired.
