"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
"This beats the pants off CQG, I am definitely switching to the ProphetX 3.0!" - Comment from Stephen
"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim
"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
"Excellent datafeed !!!" - Comment from Arely
"Everything is working great with the API. I love it." - Comment from Calvin
"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
"I just wanted to say how happy I am with your service. I was able to download the API docs last week and I was able to replicate Interactive Brokers historical bar queries and realtime bar queries over the weekend. That was about one of the fastest integrations that I've ever done and it works perfectly!!!!" - Comment from Jason via Email
"You are much better than lawyers or the phone company because you answer the phone when I call! I just love your customer service." - Comment from Isreal
"Very impressed with the quality of your feed - ******* is a real donkey in comparison." - Comment from A.C. via Email

Previous versions of IQFeed did not decrement the connection count (can't vouch for any internal code/resources) within the IQ Connection Manager once a TCP/IP-based application disconnected from it. There's no real damage done unless ~2000 connections are made. At this point, the IQ Connection Monitor does the equivalent of a Dr Watson.

Unfortunately it looks like this is still hanging around in 2.3.

I've written plenty of code to try to catch IQFeed crashes and react properly. One precaution is to make a new local TCP connection for each distinct request. If the connection fails, something is wrong. I never assume a port opened much earlier is still running and available for use. The result is many connections/disconnections. This shouldn't be an issue for DTN since these connections are all internal to my PC.

Advice?
