Connection issues with IB TWS

[smile314]

Hello,

Please help with establishing connection through NT to IB TWS. Upon connecting Interactive Brokers TWS keeps prompting for a login, then proceeds to load the GUI, after a bit of time it unloads the GUI and this happens a few times in a row. NT never shows the IB as connected in the status bar.

Thank you!

Hello,

Thank you for your post.

Please contact me at Support AT NinjaTrader DOT com. In the message please include a link to this forum thread and a copy of today's trace file.
The file is located in the Documents > NinjaTrader 7 > Trace folder. I would need the 'trace.20140514.txt' file.

Thanks for your response, Kyle. I figured the solution by searching deeper in the forums. Apparently putting "Interactive Brokers Trader Workstation" in the title solves the problem even if you don't have a White Label GUI and are a client of IB directly. I'd suggest adding this note to your instructions as it seems a lot of people run into this issue recently.

Thanks again.

I have trouble connecting to TWS.

These days I first have to start TWS, then Ninja, then connect ninja to TWS.
But from 2 weeks ago, I get error, your connection is rejected by teh computer and cannot login.

Can't connect from Ninja to TWS

Hi,

I get the following error when I try to connect to Tws from Ninja Trader.
This problem started when I upgraded to Tws 944.3

"Fatal Error: one of the following jar files is missing from the classpath:
httpcore-4.3.jar
httpclient-4.3.jar
Please make sure you run the application from the shortcut that was
installed on your desktop or on the Start menu when you upgraded."

Java for windows 7.55
Tws 944.3
Ninja 64-bit 7.0.1000.13

Thank you

Hello,

Does the same error message appear when starting TWS itself?

Can't connect from Ninja to TWS

Thanks for your response, Kyle. I can start Tws itself without going thru Ninja and no errors appear.

Thank you!

Hello Maciej,

You have an outdated version for TWS.
