"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
"I would just like to say that IQFeed version 4 is running very well and I am very happy with its performance. I would also like to extend a big thanks for the fast and efficient help that I always receive. My questions and concerns are always addressed promptly. Way to go!" - Comment from Josh in CO.
"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 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
"The service is great, I see a noticeable improvement in my volume profiles over [broker]'s data feed" - Comment from Larry
