IB TWS 10.30.1u and NT 8 version 8.1.4.2 Not working

[Taddypole]

I have just downloaded the latest release of both Trader Workstation and NinjaTrader 8. When I try to connect to InteractiveBroker, I get the following message...

"IB Paper Trading: Error in opening connection IB Paper Trading exception caught: Object reference not set to an instance of an object. (Panic)"

Are these versions compatible?

Hello Taddypole,

Thank you for posting.

With the current version of NinjaTrader please we only officially support TWS version 10.33.1b. If you are running another version of TWS please uninstall your existing version via the Windows Control Panel, and then install 10.33.1b via the following link:

• Download Here

Once TWS 10.33.1b has been installed, please ensure that the configuration in our Connection Guide for TWS has been completed at the link below.

• Interactive Brokers Connection Guide

Let me know if I may be of further assistance.
