"I would just like to say that IQFeed version 4 is running very well and I am very happy with its performance. I would also like to extend a big thanks for the fast and efficient help that I always receive. My questions and concerns are always addressed promptly. Way to go!" - Comment from Josh in CO.
"This beats the pants off CQG, I am definitely switching to the ProphetX 3.0!" - Comment from Stephen
"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 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
"Thanks for the great product and support. During this week of high volume trading, my QuoteTracker + IQ Feed setup never missed a beat. Also, thanks for your swiftness in responding to data issues. I was on ******* for a few years before I made the switch over early this year, and wish I had done it a long time ago." - Comment from Ken
"Everything is working amazing now. I'm already impressed with the true-tick feed of IQFeed and it's ability to support my 480 symbol layout." - Comment from Tyler via Email
"I "bracket trade" all major news releases and I have not found one lag or glitch with DTN.IQ feed. I am very comfortable with their feed under all typical news conditions (Fed releases, employment numbers, etc)." - Comment from Public Forum
"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
"Interactive Brokers tick data was inconsistent, so I have switched to using DTN exclusively. It is great to no longer have to worry about my datafeed all day long." - Comment from Philippe
"This is an excellent value, the system is generous (allowing for 500 stocks) and stable (and really is tick-by-tick), and the support is fantastic." - Comment from Shirin via Email

IQFeed Developer Wish List » More robust client infrastructure May 18, 2004 11:02 AM (Total replies: 0)

Here is my wish list. I can help, I’m currently working on a strongly typed DotNet field classes and factories. I’ll open it up to everyone when I’m done.
John

More robust client infrastructure:

1. Should not require applications using IQFEED to be in IQFEED distribution directory.
2. No one client application should own the IQFEED management. Once started all are peers.
3. It should be either a NT service, or COM+ singleton application.
4. On startup, logon parameters should be derived from the NT session logon, registry, etc. and not necessarily the client application (optional).
5. Strongly typed field classes. Either in COM or DotNet. with class factories to parse stream.

Hope this helps
John

IQFeed Developer Support » Lightest client solution TCP or XFeed? May 18, 2004 10:42 AM (Total replies: 0)

I'm using Visual Studio Dot Net Managed Dev in C++.

Which consumes less client resources: using IQFeedXLib and Level2Lib; or, TCP connections?

Thanks,
John

IQFeed Developer Support » Less is beter May 9, 2004 01:53 PM (Total replies: 1)

Can I get a wire protocol. I don't want to use IQFeedX or Y or Level2 exe or any other client component. Can I get a protocol msg spec to talk to the backend server?

thanks,
John
