Exegy, provider of capital markets trading technology, has announced a major update to its FPGA-based trading engine, nxAccess. The release introduces a 71% reduction in execution-stack latency, measured from start-of-packet to start-of-packet on the switch. This performance boost is designed to provide deterministic execution for firms operating in highly volatile environments where traditional hardware constraints can lead to “latency leakage” and missed pricing opportunities.
The update features a new Session Override capability, allowing firms to monitor session performance in real-time. This tool enables trading algorithms to bypass static configurations and pivot to the fastest available session or network link at the moment of execution. By turning connectivity into a dynamic asset, firms can adapt to fluctuating exchange latencies throughout the trading day without requiring complex hardware re-coding.
In addition to speed improvements, the latest version of nxAccess expands connectivity options to include UDP-based multicast and raw Ethernet frame transmission. These additions allow for immediate integration with ultra-low latency wireless and private links. As an off-the-shelf FPGA platform, the enhanced nxAccess aims to provide firms with the speed of custom hardware logic while maintaining the deployment flexibility and shorter development cycles of software-led solutions.
