"IQFeed version 4 is a real screamer compared to anything else I have seen." - Comment from Tom
"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
"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
"I used to have *******, but they are way more money for the same thing. I have had no probs with data from DTN since switching over." - Comment from Public Forum Post
"With HUGE volume on AAPL and RIMM for 2 days, everyone in a trading room was whining about freezes, crashes and lag with *******, RealTick, TS and Cyber. InvestorRT with IQFeed was rock solid. I mean SOLID!" - Comment from Public IRC Chat
"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.
"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

Having both DTN.IQ and IQFeed API installed seems incompatible.

I am using the IQ32.DLL located in the "C:\Program Files\DTN\IQFeed\" directory for my application development/API. (IQ32.DLL file version is 3.7.0.0 with size 98,304 bytes).

If DTN.IQ is running and logged on, calling RegisterClientApp() returns true (for success). However, a MessageBox pops up with the message "Error: a version of IQConnect is already running".

This is a problem because the call the RegsiterClientApp() returned true but in fact it should have returned false - a failure.

And the callback doesn't get called so there is no IQ32 status returned. Since we are relying on this status callback it should always work.

I think RegisterClientApp() should block until a successful registration is confirmed.

I cannot use the IQ32.dll in the "C:\Program Files\DTN\DTN.IQ\" directory after calling RegsiterClientApp() it pops up a message box error "Error: Cannot find IQConnect.exe" and then causes an unidentified exception. In addition there is no SetAutoLogin() function exported.


P.S. Does this mean it is impossible to run a third party application with DTN.IQ client applications running?

For now (we will be better support multiple clients connecting in the future), before calling registerclientapp, I would suggest checking of the IQconnect process is running. if so, don't call registerclientapp and instead just connect to the local socket.

Again, this is something we will be supporting much better in the future.
