I could do detailed time and sales studies...

“I have been using continuous data feeds since 1995. I started with BMI and then changed to Hyperfeed. In mid 2004, Hyperfeed notified me that by the end of the year it would take 3 dedicated T1’s bundled together to supply me with the data I was receiving and that they expected the requirements to double in time. Fortunately Eric was beginning to test his new Nanex product NxCore. I tested it and found that not only did it broadcast the same continuous data that I was receiving, but it also created a large daily file that I could do detailed time and sales studies against and it all came over the internet!” Harold Lanier , Roswell, GA

I’m totally impressed by how much this small component can do...

“I’ve been working in software development for the financial industry for over 15 years, both for European and US markets. There were many data feeds protocols and APIs passing through my dev environment, starting with market data received through TV teletext service and satellite antennas and continuing with the Internet feeds that are so common now. I’ve developed on almost every single datafeed in United States; Sungard, Comstock, Tenfore/Morningstar, Quote.com, eSignal, IQFeed, Hyperfeed, Activ Financial are the ones I can recall. I remember reading hundreds of pages of documentation sometimes spread in three or even more separate documents, with tens of appendixes and tables. I remember trying to navigate through the mess of DLLs and EXEs that some of them provided as part of their API. I remember trying to understand their sample apps, some of them including ten or more source and header files. If you don’t wish to have memories such as these (many times accompanied by frustration) and you wish to have unlimited data passing through your dev environment – NxCore is for you. My first experience was during the installation. I ran NxCore Setup and it finished a second after I clicked the install button. To be honest, I was initially thinking something went wrong and the installation silently failed – I couldn’t believe it actually installed a very powerful engine. My next experience was running it: it was running in 10MB of memory, not moving one byte more or less, and consuming zero CPU, while downloading and streaming the whole US stock and futures market on my desktop computer over a regular internet connection! I wasn’t surprised anymore when I saw that the documentation and the samples were incredible simple and straight forward. I was able to connect to the stream and process trades and quotes in my application within a half hour of coding – but this time I just expected it: after seeing how it installs, how it runs, and how incredible simple everything is, it was just it’s natural flow. While coding my applications, many times I’ve thought to myself “it would be great if NxCore would provided this…” …and bang!, after checking the documentation more carefully, it was already there! The NxCore access component and APIs are not only super-optimized, but were designed with always having in mind how the developers using it can optimize their code too. Forget about lookups through collections and dynamic memory allocation, which are killers for a real-time application: if you use NxCore at its full capacity, you don’t need even one single lookup, nor allocating one single byte of memory for an entire, 24-hour market day. An impressive and extremely helpful feature is the ability to replay a specific market day. Imagine that you have an application that crashed in production, malfunctioned or underperformed during a certain period of a hectic market day. Normally you would have to spend a lot of time to investigate the issue by inspecting log files and crash reports and detecting the cause (if you’re lucky). Too many times however the developer is left to guess the problem, attempt a fix and wait for another similar event to occur – and we know that exact same event will never occur. This is not the case if you run NxCore. You can replay that specific market day in QA how many times you want, until you recreate and fix the real problem. I’m totally impressed by how much this small component can do. Never have I seen such simplicity and such power delivered with such a small footprint and using so few resources. It has been a pleasure and a privilege to use NxCore.” Cose Craus , Nirvana Systems, Inc. - Austin, TX

Thank you Nanex for your cutting edge technology...

“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”. Jeff Smith , Spokane, WA

Every representation made of NxCore is flawlessly accurate...

“In today’s marketplace, there is no room for error, data omission, latency or excuses when it comes to market data. After we had been a customer of Hyperfeed for five years and S&P Comstock for two, I had come to the realization that to get market data “right”, I was going to have to do it myself. Our troubles with Hyperfeed and Comstock were nothing short of endless. Technology shortcomings, database misconfigurations, data losses and endless excuses. Six months into a project to build our own ticker processing plant for SIAC and OPRA feeds I somewhat accidentally ran into Nanex and NxCore. It took nothing more than a one week evaluation of NxCore for us to make the decision to terminate the new ticker plant development efforts and to make a full commitment to NxCore. This is a decision that could not have turned out better. Our trading precision has grown significantly, profits have grown and NxCore is the foundation of our data requirements. Every representation made of NxCore is flawlessly accurate. Without a doubt, Eric Hunsader is a visionary in the market data software field and has created the most useful, reliable and completely well thought out ticker plant in the industry. You can consider the rest, but choose only the best – NxCore. “ J. Brian Schaer , USA Securities

NxCore was simply the only product that could meet our need...

“Making sure that we are getting a “complete picture” of the day’s trading activity is an essential requirement for our “black box” application and website development efforts. NxCore made that possible and they did 90% of the work for us. Using the NxCore data API’s and the provided application programming templates, we were accessing the core real-time data we needed within 2 days of starting our development. If you need a complete market data feed with a powerful yet easy-to-use data API, there is simply nothing else comparable to NxCore. With other market data providers, if your data link goes down you have lost that market data forever. With NxCore we did not lose a single trade or quote message when our ISP recently experienced a major fiber outage. When the ISP connection came back up after the hour long outage, NxCore automatically downloaded the missed data and our application servers we were back running normally within 8 minutes. We didn’t even have to restart a single application. For us NxCore was simply the only product that could meet our need for complete market data access over the Internet with an easy-to-use yet powerful data API.” Greg Ferris , Former President and COO CyBerTrader Inc.

The system you’ve created is very impressive...

“The system you’ve created is very impressive! I’m already developing on it for a Federal government agency and am looking forward to analyzing the market feed in the coming weeks.” Shawn , Federal Government Developer
