"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

"I have to tell you though that using the IQFeed API is about the easiest and cleanest I have seen for some time." - 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

"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 "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

"For anyone considering using DTN.IQ for a data feed, my experience with the quality of data and the tech support has been very positive." - Comment from Public Forum

"My broker in Davenport suggested I give you a try as he uses your service and says its the best." - Comment from Bill via RT Chat

"I'm very glad I switched to IQFeed. It's working perfectly with no lag, even during fast market conditions." - Comment from Andy via Email

"I am enjoying the feed very much - so superior to the broker provided feed I was previously using." - Comment from George

"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
