"Boy, probably spent a thousand hours trying to get ******* API to work right. And now two hours to have something running with IQFeed. Hmmm, guess I was pretty stupid to fight rather than switch all this time. And have gotten more customer service from you guys already than total from them… in five years." - Comment from Jim

"I use IQ Feed, Great stuff as far as data analysis information, storage and retrieval is concerned." - Comment from Public Forum

"It’s so nice to be working with real professionals!" - Comment from Len

"I've never had DTN go out on me since switching. ******* would go down a couple times every month when I was using them." - Comment from Bryce in AL.

"Interactive Brokers tick data was inconsistent, so I have switched to using DTN exclusively. It is great to no longer have to worry about my datafeed all day long." - Comment from Philippe

"Just a quick one to say I'm very impressed so far :) The documentation for developers is excellent and I've quickly managed to get an app written to do historical downloads. The system is very robust and pretty quick considering the extent of data that's available. The support guys have been very helpful too, in combination with the forums it's been plain sailing so far!" - Comment from Adam
