Ever since I upgraded to the latest IQFeed, v4.6.1.0, it has been crashing occasionally on me: Every few hours, and only during market hours. The crash comes with a standard Windows error message, "This program ... must be shut down." (I can get the exact wording if you need, but it is nothing special).

I only use IQFeed with QuoteTracker, the latest version 3.9.5 . The previous version of IQFeed I had,, never had any troubles even once.

Helllp :)

I'm using Windows XP Professional x64 Edition, version 2003 SP2, in an Administrator account.

Hello Mike, with this error message, does IQFeed shut down or does QT or both? How many symbols are you tracking within QT, i.e; how many on the portfolio page, how many charts do you have open and how many studies per chart?

Only IQFeed crashes.

I was always tracking about 15-25 symbols using; 15-20 of those had charts open; and just the basic data for each chart: quote and volume.

I occasionally backfill a chart using IQFeed: using either "tick backfill" or non-tick (consolidated 15-second) backfill. This last market session I actually experienced no crashes.
