"I've been using IQFeed 4 in a multi-threaded situation for the last week or two on 2600 symbols or so with 100 simultaneous daily charts, and I have had 100% responsiveness." - Comment from Scott
"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 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
"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
"Thank you so much - awesome feed, awesome service!" - Comment from Greg via Email

"I just wanted to tell you what a fine job you have been doing. While *******, from what I hear, has been down and out, off and on, IQ feed has held like a champ this week." - Comment from Shirin
"I started a trial a few weeks back before the market went wild. DTN.IQ didn’t miss anything and beat my other provider. I decided to stay with you because of the great service through all the volatility." - Comment from Mike
"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

DTN.IQ Client Software Support » How to prevent disconnection IQLink Jul 5, 2010 12:23 AM (Total replies: 2)

Hello I have a question
I want to collect data from IQFeed Client (I installed the latest version) via DDE
To do this, I run IQLinkLauncher, click "Start IQLink" (there is a connection to the server) then I close the window IQLinkLauncher. I see two icons: IQConnectionManager and DDE. Then I turn on my program which collects data via DDE

Everything works fine, but ... As soon as I disable the program, the connection IQFeed client to the server, too, disappears (disappearing icons IQConnectionManager and DDE). I have to re-run IQLinkLauncher, that would reconnect

The same thing happens if I'm taking data from DDE in Excel. One has only to shut down Excel, as icons IQConnectionManager and DDE disappear. Can you please tell how to make that connection would not lost even if I temporarily disable programs that take data on DDE? And yet you please tell, how do I organize automatic connections (which would not have to press the button "Start IQLink" in IQLinkLauncher?
