"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
"You are much better than lawyers or the phone company because you answer the phone when I call! I just love your customer service." - Comment from Isreal
"DTN feed was the only feed that consistently matched Bloomberg feed for BID/ASK data verification work these past years......DTN feed is a must for my supply & demand based trading using Cumulative Delta" - Comment from Public Forum Post
"I ran your IQFeed DDE vs. my broker vs. a level II window for some slow-moving options. I would see the level II quote change, then your feed update instantaneously. My broker's DDE, however, would take as much as 30 seconds to update. I am not chasing milliseconds, but half a minute is unacceptable." - Comment from Rob
"Thank you so much - awesome feed, awesome service!" - Comment from Greg via Email

DTN.IQ Client Software Support » V4 Crashes Dec 8, 2005 01:50 AM (Total replies: 2)

Hi Jay,

> I assume the crash occurs when using your internally developed software?
Yes, that is correct.

> There is a documented memory problem in 4.0 using sockets to request numerous history requests.
That could be related - I am using using sockets to communicate with IQFeed.

> Take a look at the 4.0 documenation regarding the registry settings to change to turn on logging in IQFeed.
Ok, I will give it a try and get back to you if something comes up :)

> Also, is the crash in IQFeed/IQConnect or in your software?
The crash is definitely in IQConnect. After running for a few hours, Windows say 'IQConnect.exe performed a illegal operation and must be closed'. Once I click 'close' to terminate IQConnect, my application recovers normally from disconnection, IQConnect is reinstantiated and everything is fine again.

Thanks a lot! :)

DTN.IQ Client Software Support » V4 Crashes Dec 3, 2005 12:27 PM (Total replies: 2)

Hi there,

Since I upgraded to V4 I am experiencing periodic IQConnect crashes. I am pretty clueless about what could be causing it due the lack of debug information.

Here is the test cycle I was executing:

1. Application startup
2. Connect IQFeed
3. Request historic information for 175 symbols
4. Receive and process historic information for each symbol
5. Subscribe for streaming the same 175 symbols
6. Let it run 24 hours x 5 days

Unfortunately, the IQConnect crash is guaranteed to happen on the first three hours after all historic data is received. Because the crash is a 'hard' windows crash that invokes the 'this program executed an illegal operation' dialog, my application cannot recover from it until someone press the 'close application' button in the dialog.

Any ideas about what is going on? Is there anyway I can get IQConnect to spit debug information?

Thanks a lot!
