"I was on the phone with a friend who uses CQG and right after the Fed announcement, CQG was as much as 30 seconds behind DTN.IQ. Some quotes were off by as much as 15-18 cents. Your feed never missed a beat." - Comment from Roger
"I will tell others who want to go into trading that DTN ProphetX is an invaluable tool, I don't think anyone can trade without it..." - Comment from Luther
"I am very pleased with the DTNIQ system for quotes and news." - Comment from Larry
"Just a thank you for the very helpful and prompt assistance and services. You provided me with noticeably superior service in my setup compared to a couple of other options I had looked at." - Comment from John
"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 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
"IQ feed is brilliant. The support is mind-bending. What service!" - Comment from Public Forum Post
"If someone needs the best quality data and backfill beyond what their broker provides at a rate that is the best in the industry, I highly recommend IQFeed." - Comment from Josh via Public Forum
"Thank God for your Data Feed as the only Zippers I see are on my pants (LOL), and no more 200 pip spikes to mess up charts." - Comment from Spiro via Email
"I've been using Neoticker RT with IQFeed for two months, and I'm very happy with both of the products (I've had IQFeed for two years with very few complaints). The service from both companies is exceptional." - Comment from Public Forum
