"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim

New IQFeed Forum » Connecting to IQFeed data freezes NinjaTrader Apr 12, 2023 02:07 PM (Total replies: 3)

This was an issue several colleagues were dealing with, with seemingly no explanation or resolution.

Simply connecting to the IQFeed data would cause NinjaTrader to lock/freeze and require a force stop.

It was finally discovered this was due to a port conflict with the IQFeed client software. Uninstalling or disabling any other program running on your computer that uses port 9100 should resolve this issue.

A known example of this is Logitech G Hub (GHub).

This took quite some time and headache to diagnose, and surprisingly is not mentioned here, and DTN Support does not seem aware of this issue. So I figured having this post here might help some folks in the future.
