NinjaTrader 8 cannot connect to Interactive Brokers TWS

[rgoudie]

I have searched the support forums and could not find anything that relates to my particular issue.

I signed up for a trial account with Interactive Brokers. I created a new connection for Interactive brokers following the steps in the recommend article. I cannot connect. Can you assist?

NinjaTrader is able to launch TWS and successfully login, but the icon in the bottom right-hand corner of NinjaTrader remains yellow for a minute or so, then the following error message appears:





Here is my Interactive Brokers connection information in NinjaTrader:
The Auto login path correctly points to the installed version of tws.exe.




Here is the API settings information in TWS:




NinjaTrader version: 8.0.21.1 64-bit
Trader Workstation version: 973.2

I have tried setting the Port TWS value equal to the Socket Port value, but that resulted in an immediate error.

Thanks.

I managed to solve my issue.

In my previous attempts, I had tried setting the Port TWS value in NinjaTrader to the Socket port value in TWS. This did not work and resulted in an immediate error.

I just tried the reverse: setting the Socket port value in TWS to the Port TWS value in NinjaTrader. This worked! I am not sure why this assignment worked and the previous did not. Perhaps it is a question of reserved port numbers.

Nope. Still cannot connect to TWS from NinjaTrader. I was able to connect that one time. Today, I cannot connect at all. The socket port has not changed since that single successful connection.

Would you have any further ideas? Thanks.

I simply installed and started to use IB Gateway 972.
I was never able to connect using IB TWS 973.

I'm having the same issues. Was there a resolution?

Thanks for the tip. I was able to get to work with IB Gateway 978.
