  • The buy-side dealing and execution services specialist has selected eflow’s trade surveillance technology and xyt’s Transaction Cost Analysis (TCA) and Execution Intelligence to modernise its regulatory tech stack

  • Partnership reflects growing demand for integrated surveillance and analytics as best execution scrutiny intensifies across buy-side firms 

 

9am London BST, 22 July, 2026eflow and xyt today announce that Greenwich Dealing, the Geneva-based buy-side Outsourced Dealing services provider, has selected their respective regulatory solutions to strengthen oversight of its execution activity and compliance processes. 

Greenwich Dealing operates as an independent, outsourced specialist provider for institutional investors across global markets, managing relationships with over 150 brokers, investment banks and alternative platforms whilst also providing relevant market intelligence and valuable advice on both pre and post-trade-related issues. 

The firm selected the combined solution to strengthen oversight of their execution quality, broker performance and regulatory compliance. This decision comes against a backdrop of regulators placing increasing emphasis on transparency around broker selection and the detailed rationale that underpins a firm’s trade surveillance strategy.

eflow’s technology provides Greenwich Dealing with comprehensive trade surveillance across its dealing operations, delivering structured oversight of pre and post-trading activity and regulatory risk. xyt’s independent trading data intelligence platform extends this capability through tick-level transaction cost analysis across over 120 global venues, alongside customised execution reporting and broker performance measurement grounded in addressable liquidity data. The collaboration is underpinned by a shared strategic alignment, with both eflow and xyt forming part of the Finch Capital portfolio.

Together, both market-leading solutions enable Greenwich Dealing to oversee execution quality with regulatory confidence, while supporting broker selection processes with data-driven performance analysis tailored to individual client reporting standards under MiFID II.

Maxence Boniol, Head of Execution Trading at Greenwich Dealing, commented: "Our regulatory strategy demands both rigorous trade surveillance and granular analysis of execution outcomes. We selected eflow and xyt for the strength and breadth of their market data coverage, which gives us the depth of oversight required to monitor market abuse and best execution. Their flexibility further allows us to maintain the consistent, high-quality regulatory reporting that institutional execution services demand. Just as importantly, the granularity of their execution analytics enhances our ability to refine broker performance feedback and measure order impact across markets, sharpening the precision of our offering. Together, these technologies reinforce our commitment to the highest regulatory standards in institutional execution."

Franck Chatillon, Senior Founding Partner at Greenwich Dealing, commented: “This partnership with xyt and eflow will further strengthen the quality of our offering, enabling us to provide our clients with an even more effective response to the growing regulatory requirements they face. By combining our expertise and technology, we are helping clients meet their compliance obligations more efficiently while enhancing the overall quality of our services."

Robin Mess, CEO at xyt, commented: “We believe the future lies in bringing together execution intelligence and regulatory oversight. Greenwich Dealing recognised the value of combining xyt's independent trading analytics with eflow's surveillance expertise to create a more complete view of execution quality, broker performance and compliance. Together, we are helping firms make more informed decisions while maintaining the highest regulatory standards.”

Ben Parker, CEO of eflow, added: “Greenwich Dealing's selection of eflow’s trade surveillance technology reflects how buy-side firms are evolving their compliance approach. Their need for comprehensive oversight of their market abuse risk, coupled with a system that can evolve and adapt to changing business needs meant that our solution was a perfect fit. Our partnership with xyt demonstrates how specialist providers working together can deliver precisely what firms need to remain compliant and competitive without compromising on quality.”
