"Previously I was using *******. IQFeed is WAY more economical, and for my charting needs is just as good, if not better." - Comment from Public Forum Post

"I've never had DTN go out on me since switching. ******* would go down a couple times every month when I was using them." - Comment from Bryce in AL.

"I just wanted to tell you what a fine job you have been doing. While *******, from what I hear, has been down and out, off and on, IQ feed has held like a champ this week." - Comment from Shirin

"There is no doubt that IQFeed is the best data provider. I am very satisfied with your services. And IQFeed is the only one that I would recommend to my friends. Now, most of them are using your product in China." - Comment from Zhezhe

"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam

"Excellent datafeed !!!" - Comment from Arely

"You have an excellent product !!!!!!" - Comment from Arely

"Awesome response, as usual. It is a sincere and refreshing pleasure to do business with DTN, compared to your competition." - Comment from Ryan

"I'm satisfied with IQFeed. It's the most reliable and fastest quote feed I have ever used. Although I'm a resident in China, it's still very fast!" - Comment from Xiaofei

"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

Here is what I did: - download and install IQFeed 2.3 - I did not subscribe on any live market data, just delayed data only (not sure if this matters) - build and run the "CSharpLevel1Com" sample - unfortunately the text box to enter a symbol still is disabled, since the "IQFeed_SystemMessage" method is not triggered Here is more information: - on startup the IQ Connection Manager shows up in the system tray for a second and disappears immediately - I experience the same on starting the pre-build VB "History COM client" - the VB "History socket client" is fine: the "IQ Connection Manager" stays in the system tray - the Java sample also is fine Am I doing something wrong here ? Any comment is appreciated. Regards Dierk Droth www.trademagic.net TradeMagic - Trading at its best Edited by Dierk Droth on Aug 16, 2004 at 11:13 AM

There is an issue with the IQFeedY control that causes applications using IQFeedY to lose their connection. The CSharp and History COM apps also use IQFeedY, thus the issue. You can work around this issue by using sockets, or using COM directly (not the IQFeedY control). We are working on a fix, but I do not have an ETA. Thanks! Natalie Hannan DTN Market Access, LLC.
