"After all the anxiety I had with my previous data provider it is a relief not to have to worry about data speed and integrity." - Comment from Eamonn

"Everything is working great ! Very impressive client. The news refreshes better and is more pertinent than the ******* feed I paid $ 100/month for. I Also like the charts a lot." - Comment from Leon

"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.

"And by the way, have to say this. I love the IQFeed software. It's rock solid and it has a really nice API." - Comment from Thomas via RT Chat

"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum

"I'm very glad I switched to IQFeed. It's working perfectly with no lag, even during fast market conditions." - Comment from Andy via Email

"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

"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 was with ******* for 4 years at $230 a month, this is a huge savings for me, GOD BLESS YOU PEOPLE," - Comment from T.S. via Email

"I just wanted to let you know how fast and easy I found it to integrate IQFeed into our existing Java code using your JNI client. In my experience, such things almost never go so smoothly - great job!" - Comment from Nate

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.
