"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
"Everything is working great ! Very impressive client. The news refreshes better and is more pertinent than the ******* feed I paid $ 100/month for. I Also like the charts a lot." - Comment from Leon
"I'm satisfied with IQFeed. It's the most reliable and fastest quote feed I have ever used. Although I'm a resident in China, it's still very fast!" - Comment from Xiaofei
"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 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
"I had always used ******* but for the past 2 weeks have been trying DTN IQFeed. Customer support has been extraordinary. They call just to make sure your problem hasn't recurred." - Comment from Public Forum
"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
"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
"Thanks for following up with me. You guys do a great job in tech support." - Comment from Phelps
"I use IQ Feed, Great stuff as far as data analysis information, storage and retrieval is concerned." - Comment from Public Forum
