What is nxFeed ?

nxFeed is a feed handler which streamlines market data application development by processing data feeds on FPGA and making them available to applications via a simple, normalized API.

Designed to complement trading applications or in-house ticker plant development, nxFeed will arbitrate, decode, normalize and build order books on a plug-n-play, FPGA-based NIC — significantly reducing application processing resources and overall latency. This allows developers to focus on what they do best – build core business logic.

nxFeed reduces market data processing latency and server footprint compared to software-based solutions while also providing the flexibility for deployment as an in-application architecture using PCIe or distributed via UDP multicast over Ethernet.

Who should use nxFeed?

Frequently used by electronic trading applications or normalized data processing systems — nxFeed has the flexibility and power to process raw market data from even the most volatile exchange feeds.

Designed to be a tool in any market data developers toolbox nxFeed is easy to integrate with new or existing applications. nxFeed provides data processing with plug-and-play, FPGA-enabled market data handling and a simple C++ API.

When used for algorithmic trading, integrating nxFeed is often a first step towards end-to-end FPGA-based trading strategies using nxAccess, the Enyx execution engine with an embedded FPGA algorithm sandbox and accelerated execution capabilities.

How is nxFeed unique?

» PERFORMANCE 

With constant, deterministic, and jitter-free performance, nxFeed filters unnecessary data and increases overall performance by reducing the network and server load. Whether publishing updates to a local application via PCIe or over the network to remote applications — nxFeed guarantees consistent and transparent performance.

» PRODUCTION READY

With software simulators available to aid the development cycle — the path to integrating with the nxFeed API is simple and can be achieved in as little as a week. There is no requirement to install dedicated FPGA hardware, allowing firms to maximize time-to-production for their applications.

With an easy-to-use API, nxFeed offers features that were typically reserved only for software solutions:

• TCP-based remote application resynchronization
• Centralized dictionary management
• Centralized application administration & management
• Live monitoring counter & latency statistics

» PORTABLE 

By taking advantage of the portability of FPGA-based NIC, nxFeed can be deployed alongside your application on the same server, or as a feed handler serving data to many remote applications.

nxFeed is designed to easily scale from single server to multi-site trading infrastructures by including two types of access via a single API:

• PCIe local delivery for an application running on the host server
• UDP Multicast over Ethernet distribution for up to 8 different normalized feeds

nxFeed: Use cases

» In-house tickerplant

• Internal data distribution without having to normalize and build books for each exchange format
• Single, simple, normalized API delivered to existing software application stacks

» ULL trading application

• Delivery of market data updates over PCIe to application via C++ API
• Lowest latency configuration
• Initial step towards nxAccess — an FPGA-based trading engine

» Market data vendor distribution

• Leverage nxFeed to normalize data and distribute only what is required over network locations
• Simple, consistent client API for receipt of data

» Service provider: value added data feed

• Use nxFeed to generate proprietary data feeds from market data sources
• One consistent model across all exchanges
• Typical deployments include consolidated order books or SIP generation
