New nxAccess capabilities enable firms to dynamically switch to the fastest available exchange session and private links in real-time.

NEW YORK and ST. LOUIS – April 8, 2026 – Exegy, a leading provider of market data, trading technology, and managed services for the capital markets, today announced a significant performance enhancement to nxAccess, its FPGA-based trading engine. The update introduces the Session Override feature and expanded connectivity options, delivering an impressive 71% reduction in execution-stack latency to help firms capture every market opportunity.

As electronic trading infrastructure grows increasingly complex, the ability to choose the optimal path to local and remote venues is a significant driver of execution performance. The latest evolution of nxAccess addresses this by giving firms the agility to bypass traditional hardware constraints and pivot to the fastest available session or network link at the moment of execution.

“In today’s fragmented markets, the fastest route at market open isn’t necessarily the fastest at midday. Relying on static configurations creates ‘latency leakage’ that firms can no longer afford. nxAccess bridges this gap by turning connectivity into a dynamic asset rather than a hardware bottleneck,” said Olivier Cousin, Director of Product, FPGA Solutions at Exegy. “This reduction allows firms to maintain deterministic performance even during high-burst volatility, ensuring orders are filled at intended prices.”

The centerpiece of this release is Session Override, a built-in capability of nxAccess that allows firms to monitor session performance in real-time. Because local exchange latency can fluctuate throughout the day, Session Override enables an algorithm to select the best-performing session the instant a trigger occurs.

Key benefits and enhancements of the new nxAccess release include:

• ‌Dramatic Latency Improvement: Achieves up to a 71% reduction in execution-stack latency, measured from Start-Of-Packet (SOP) to Start-Of-Packet (SOP) on the switch, ensuring deterministic performance for the most demanding environments.
• ‌Dynamic Session Optimization: The new Session Override feature allows firms to use their own software to measure session performance in real-time and automatically pivot to the fastest available path without the need for hardware re-coding.
• ‌Expanded Connectivity for Premium Links: Beyond standard TCP, nxAccess now supports UDP-based multicast and raw Ethernet frame transmission “out of the box”, allowing firms to leverage ultra-low latency wireless and private links immediately.
• ‌Accelerated Time-to-Production: As an off-the-shelf FPGA platform, nxAccess combines the raw speed of hardware with the flexibility of software, allowing firms to deploy these performance improvements without the long development cycles typical of custom FPGA builds.

nxAccess is Exegy’s premier FPGA-based trading engine, designed to load order templates via software while using hardware-level logic to trigger, update, and transmit orders with nanosecond precision.

March 30, 2026 – NZX is pleased to announce the launch of the S&P/NZX 20 Index Futures on April 28, 2026, providing investors with a low-cost hedging tool to manage risk or gain exposure to New Zealand’s equity markets.

Index futures are exchange-traded contracts that lock in a price for exposure to the S&P/NZX 20 Index, with settlement on a set date in the future. On expiry, the contract is cash settled based on the index level, so gains or losses reflect how the index has moved over the contract term. This will allow investors, including KiwiSaver funds, to adjust their New Zealand equity exposure as markets change, while helping support trading activity and liquidity in NZX listed companies. New Zealand has been an outlier among first-world economies in not having liquid index futures markets, especially when comparing against other similar developed economies such as Poland, Portugal and Sweden.

People talk about “latency” in markets like it’s inherently suspicious. We think that’s the wrong frame. The real issue isn’t speed; it’s synchronicity: how quickly different points of view converge on the same market reality. Questions I hear often go something like this:

Why does speed matter? Isn’t low latency a bad thing? Should firms that build faster connectivity even exist?

I think the word “speed” (or “latency”) has been successfully framed as a moral issue. It is not. It is an engineering reality inside any distributed system.

So, let’s use the better word:

Synchronicity.

In the early 2010s many financial firms continued an ancient human tradition: shrinking the time it takes to learn about new information in order to manage risk sooner. This time, it was a race to build wireless infrastructure to interconnect key financial venues. Fast forward to today, and as is typical with sprints like this, there was heavy attrition. Very few were successful at doing it at scale.

Lots of stories to tell about this journey some day, but, the net of it is McKay Brothers became the independent commercial champion building and operating such infrastructure, and I believe it is substantially because of our commitment to operate a level playing field platform where all market participants can access the same experience of markets.

If you are wondering how broad “infrastructure” gets for us, it ranges from digging holes for the foundations of 200 foot tall cell towers to programming our own FPGAs. Yes, really. The team is an amazing diversity of backgrounds, and somehow we vibe incredibly well.
