CHICAGO (Sept. 18, 2018) – Rival Systems (Rival), an award-winning provider of trading and risk management software, today announced the release of their Options Price Reporting Authority (OPRA) feed handler within its Rival Trader platform. Rival’s OPRA feed handler runs on a 16-core server with Solarflare’s ubiquitous and hardened Onload® high performance network stack to process the entire feed without dropping any packets.

“We’re excited to offer clients access to the consolidated view of the equity options markets through the OPRA feed,” said Robert D’Arco, CEO of Rival Systems. “With our market data feed handlers, multi-broker order and execution management system, and best-of-breed analytics, we provide a truly comprehensive solution for trading equity options. As data rates increase, it’s critical for us to provide clients with a scalable software-based solution to reduce their hardware footprint and decrease latency without having to pay up for an FPGA solution. I’m extremely proud of our engineering team for their hard work, ingenuity and iterative approach to optimizing our feed handlers.”

The performance of Rival’s fully-hosted solution is enhanced by Solarflare’s Onload stack in combination with top-of-the-line servers collocated in all major data centers to provide clients with a cost-effective solution for trading futures, equities, and options. The OPRA release complements Rival’s existing CTA, UTP, CME, ICE, CBOE, CFE, NFX and Eurex feed handlers.

“Solarflare’s flagship software stack, Onload, provides an industry-standard TCP/IP stack utilizing POSIX compliant APIs, to enable full kernel bypass — allowing Rival’s well-designed and implemented OPRA feed handler to take full advantage of its capabilities,” said Russell Stern, President and CEO of Solarflare. “Rival’s technology is very impressive, and the combination of our decade-plus hardened Onload stack, our low-level abstraction layers and Rival’s smart design, provides customers with a powerful, cost-effective solution across the financial markets.”
