Horizon Goes Live with H3 Trading Platform

Subscribe to our newsletter

Horizon Software, the trading technology vendor, has launched its Horizon H3 Trading Platform, with clients now live in Europe, Asia Pacific and the Middle East.

Earlier this year, Sagard NewGen acquired a majority stake in the company, alongside a management buy-out, to support expansion into new markets and strategic capabilities. At the time of the acquisition, Horizon announced that it planned to focus on expanding its Trading-as-a-Service offering, bringing together agency trading and market making on one platform, and on scaling up its asset class coverage to include digital assets.

H3 represents the next generation of Horizon’s single cross-asset platform, based on a distributed, modular architecture with public APIs for each service. The new version supports both principle and agency trading, with the ability to scale for large volumes of executions. It also provides new functionality such as a composite spreader, workflows for both high touch and DMA, support for digital assets, and is designed for deployment in a managed services environment.

“More than 17 clients have gone live with H3 smoothly,” said Olivier Masdebrieu, CTO at Horizon Software. “We are constantly looking to enhance our platform by enriching its functionality, as well as investing on the technical side. The next significant milestone will be integrating Aeron, an open-source message transport solution focused on performance and reliability.”

Aeron was originally designed and developed by Real Logic, a low-latency trading technology development firm founded by high-performance computing specialist Martin Thompson, and acquired by Adaptive Financial Consulting earlier this year.

“This project is a step forward to better serve our clients worldwide and offer them an improved experience,” commented Guillaume Poitevin, Global Head of Sales at Horizon Software. “H3 has a services-oriented architecture that provides various performance improvements regarding scalability, latency, and on demand loading. We are proud of this new version, demonstrating our commitment to deliver the best trading services for our clients”.
