"The service is great, I see a noticeable improvement in my volume profiles over [broker]'s data feed" - Comment from Larry

"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

"You are either overstaffed or people just don't have problems with your feed because customer support always answers the phone quickly." - Comment from Jay via Email

"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 am a hedge fund manager here. It’s funny, I have a Bloomberg terminal and a Bridge feed, but I still like having my DTN feed!" - Comment from Feras

"Thanks for all of your help. Great customer service deserves to be recognized which one the reasons I've been a customer of DTN for over 10 years!" - Comment from Stuart

"I noticed that ******* quotes locked up shortly after the interest rate announcement yesterday while yours stayed stable." - Comment from Ron in Utah

"DTN has never given me problems. It is incredibly stable. In fact I've occasionally lost the data feed from Interactive Brokers, but still been able to trade because I'm getting good data from DTN." - Comment from Leighton

"And by the way, have to say this. I love the IQFeed software. It's rock solid and it has a really nice API." - Comment from Thomas via RT Chat
