Strategy failing when routing orders via IB when using v42

[scalp]

I have a strategy which execute orders and up until a prior version of NT 7 (I think version 40?) it was working fine. However, now on version 42/43 it is failing when routing orders via Interactive Brokers. Orders work fine through SIM101.

Has anything changed in the way that NT7 implements the IB connection? I am running TWS 973.2h

Here is a snippet of the log showing the errors generated, it seems to be trying to convert everything to integers?

Hello scalp,

Thank you for your note.

As of NinjaTrader 7 version 7.0.1000.41, the required version of TWS is Traders Workstation (TWS) version 978.2c.

You can download the correct version from this link: Download

Please uninstall your current TWS version, install the above one, and then test. Do you see the same errors occurring?

Thanks in advance; I look forward to assisting you further.

Many thanks Kate, that resolved the issue. I didn't see anywhere a need to update TWS. Maybe this can be included somewhere in the upgrade process if an active IB connection is detected?

Just a thought...all the best,
