Control Center unresponsive when connected to IQFeed

[nicbizz]

Hi,

I'm encountering an issue whereupon immediately after a successful connection to IQFeed, the Control Center becomes unresponsive. I can't select any options or tab, move the window, or even close Ninjatrader. All the other windows respond as normal (charts, Market Analyzer, Strategy Analyzer, etc). It's only the Control Center window that's not interactable.

For reference, I'm using Ninjatrader 8 ver. 8.1.3.1 64-bit and IQFeed Client Software version 6.1.0.20.

When I tried to close NT8 by right-clicking on Taskbar and and "Close Window", the following window pops up:


Unfortunately, I'm unable to click on the Yes or No either. The only way to shut it down is by End Task through the Task Manager.

All those error messages in the Log prompted me to try something, which was to start up a new workspace without anything (my existing workspace had some charts and a Market Analyzer with about 100 symbols) before connecting to IQFeed. Surprisingly, the issue disappeared, and I can continue using NT8 normally after connection (including opening new charts, etc).

Any idea what's causing the issue and how to resolve it? It's not very feasible to close all charts and MA each time I want to connect to the server.

Thanks.

Hello Nick,

Thank you for posting.

Can you please confirm you have IQFeed Client Software version 6.1.0.20 installed which is required for use with NinjaTrader. If you have another version installed please close NinjaTrader->Uninstall your current version then install version 6.1.0.20 at the link below:

Hi Christopher,

Any other ideas on what may be causing the issues?

Working with the IQFeed support staff, I've found the source of the problem. Leaving it here in case anyone else encounters the same issue.

The IQFeed software conflicts with Logitech G Hub, because both use port 9100. Removing Logitech G Hub resolves the issue.

Also, it appears that we can use v6.2.0.25 of IQFeed with NT8 as well, which is better since its 64bit.
