“I have been in the financial markets for over 20 years. I have tried all kinds of software and data products. Just like everything else in the marketplace the “sales pitch” is usually far from the actual experience. There are other testimonials about NxCore and how wonderful the data feed is and how easy it is to use (I was up and running in a couple of days). I agree with everything “technical” that you can read in all the other testimonials – NxCore, as a product, is truly amazing. However, it is my expectation that something that is advertised to work – WILL WORK – AND will work as advertised. Obviously, NxCore works as advertised. BUT, where NxCore is vastly differently from “the rest” is their customer service AFTER the sale. I have had my share of issues (all except one were my errors), but each time I contacted Eric for help he accommodated me quickly, efficiently and “happily” – even when I had made some stupid mistakes in my software and blamed the NxCore product. (Which is what all programmers do right? “It can’t be my software!!!”) Nanex’s commitment to supporting me on an ongoing basis is just as important to me as the quality of their product. Thank you Nanex for your “cutting edge technology” and your “very old-fashioned customer service”.”
