"Previously I was using *******. IQFeed is WAY more economical, and for my charting needs is just as good, if not better." - Comment from Public Forum Post

"I am very happy I changed. I love the product, but more so I am thrilled with Tech Support. You are knowledgeable, polite, pleasant and professional." - Comment from Pat

"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

"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

"If you are serious about your trading I would not rely on IB data for serious daytrading. Took me a while to justify the cost of IQ Feed and in the end, it's just a 2 point stop on ES. Better safe than sorry" - Comment from Public Forum

"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

"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

"Everything is working amazing now. I'm already impressed with the true-tick feed of IQFeed and it's ability to support my 480 symbol layout." - Comment from Tyler via Email

"I like you guys better than *******...much more stable and a whole lot fewer issues." - Comment from Philip

"Awesome response, as usual. It is a sincere and refreshing pleasure to do business with DTN, compared to your competition." - Comment from Ryan

You seem to provide more data for a stock via TCP/IP Historical (thanks!). 2. Volumes (and some prices) provided for TCP/IP Historical is always different between the two servers. Not by much, but a couple of thousand shares. Here is Microsoft 60 minute data from the new servers: 2007-06-07 07:00:00,30.1600,30.1600,30.1600,30.1600,100,100; 2007-06-07 09:00:00,30.2800,30.2100,30.2100,30.2700,16850,16750; 2007-06-07 10:00:00,30.2900,30.0000,30.2600,30.2100,9005266,8988416; 2007-06-07 11:00:00,30.2200,30.0400,30.2000,30.1300,17956795,8951829; 2007-06-07 12:00:00,30.1700,30.0500,30.1300,30.1300,23974269,6016474; 2007-06-07 13:00:00,30.1800,29.9400,30.1300,30.0300,31509952,7535683; 2007-06-07 14:00:00,30.0700,29.6600,30.0300,29.7673,43974765,12446653; 2007-06-07 15:00:00,29.8600,29.7200,29.7700,29.7800,52299461,8324696; 2007-06-07 16:00:00,29.7900,29.7500,29.7800,29.7600,52760660,461199; Here is from the old servers: 2007-06-07 10:00:00,30.2900,30.0000,30.0200,30.2100,9005366,7452192; 2007-06-07 11:00:00,30.2200,30.0400,30.2000,30.1300,17956795,8951629; 2007-06-07 12:00:00,30.1700,30.0500,30.1300,30.1300,23984769,5857759; 2007-06-07 13:00:00,30.1800,29.9400,30.1300,30.0300,31523752,7038683; 2007-06-07 14:00:00,30.0700,29.6600,30.0300,29.7673,43980765,11451845; 2007-06-07 15:00:00,29.8600,29.7200,29.7700,29.7800,52307661,8276267; 2007-06-07 16:00:00,29.9100,29.5900,29.7800,29.6000,68184946,15820585; 2007-06-07 17:00:00,29.6200,29.6000,29.6000,29.6200,69439784,1239338; Are they using the same datasource?
