"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 was on the phone with a friend who uses CQG and right after the Fed announcement, CQG was as much as 30 seconds behind DTN.IQ. Some quotes were off by as much as 15-18 cents. Your feed never missed a beat." - Comment from Roger

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 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.
