Nanex is the creator and developer of NxCore, a streaming whole market
datafeed with an easy to use API. Nanex supports NxCore and develops
applications that run on the NxCore platform.
NxCore (pronounced n'core) is a high-performance, real-time streaming
datafeed (ticker plant) that brings the whole market to your workstation or
desktop computer. NxCore excels in delivering and databasing all the quotes and
trades transmitted by the exchanges, even in the hyper-active U.S. Option
market (OPRA) which now transmits over 4,500,000 quotes per second, and 8
billion quotes per trading day.

NxCore
has an easy to use API for developing trading software. No parsing
required, it uses simple fixed structures and includes important and frequently
used information in every quote and trade update. NxCore includes tools to help
you visualize and understand data relationships in the feed. And NxCore lets
you replay the data at blazing speeds (2 million+ updates/second) on
inexpensive hardware. Converting from existing feeds becomes a trivial
exercise.
NxCore databases everything; all quotes,
trades and other real-time updates are stored on your computer. If you are
developing or have your own in-house ticker plant, NxCore is ideal for
evaluating your ticker's output performance and data integrity. NxCore also
makes an ideal back-up feed, ready to go online should your primary feed fail
or require down-time. |
NxCore requires minimal
resources . Unlike some datafeeds that require hardware costing over
$10,000, NxCore can run on a low-end Pentium laptop (1.0 GHz, 256MB of RAM,
80GB IDE hard drive) and receive and database 4,500,000 quotes/second, over 8
billion/day; and CPU usage will remain under 5%
NxCore is extremely efficient in bandwidth
utilization and will save you thousands of dollars in monthly communications
costs. In a single T-1 (1.5mbps), it will fit 40,000 quote and trade updates
per second; In 6.0 mbps, it will fit 160,000 updates/sec. Other OPRA feed
providers now require a T-3 (30 T-1 lines) and yet provide less information per
update than NxCore. Plus, NxCore offers an optional BBO only stream for OPRA
data that is 40% smaller than the full OPRA stream. |

Nanex currently offers historical market
data from January 2004 to the present day. The data is in the NxCore
tape file format. There are three major benefits for doing it this way. It's in
the exact same format as the data during real time. All the
data is synchronized, unlike other data services that provide
data by symbol and then one has to synch all symbols and guess which quote came
before the trade. It's compressed over 90%, saving hard drive
space and time. Nanex has the ability to create tapes with only information
that is necessary. Tapes can be trades only from one exchange or all exchanges
that we offer. Checkout the historical page for more details! |
