OpenDoor selects Esprow ETP Studio to automate testing of their FIX connectivity

New York, 24th September 2020 – Esprow LLC, a leading global provider of testing and compliance automation solutions for the financial industry, has today announced that OpenDoor Securities LLC, provider of the only anonymous dark, all-to-all trading venue for both current and off-the- run U.S. Treasuries and TIPS, has adopted Esprow ETP Studio for automated testing of their FIX connectivity.

Esprow ETP Studio is the industry’s leading solution for FIX protocol testing. ETP Studio provides sophisticated tools to execute FIX regression testing and FIX ad-hoc testing of FIX-based trading systems. Launched 8 years ago, ETP Studio was quickly adopted by enterprise financial institutions in North America, EMEA, and APAC due to its unique multi-protocol support for FIX and binary protocols, its active development roadmap, and because of its premium follow-the- sun support services offered by Esprow offices in Japan, Singapore, St. Petersburg, and New York. As a result of this engagement, OpenDoor Securities was able to carry out testing and maintain the reliability of its FIX trading APIs.

Josh Holden, CIO at OpenDoor Trading, comments: "In today's markets, clients value data, order routing and STP more than ever, and a robust FIX framework has become a requirement. Esprow ETP Studio has proven invaluable in our efforts to rapidly deliver our FIX connectivity to a wide variety of clients and stakeholders."

Francesco Lo Conte, Managing Director at Esprow in New York, comments: "Like many forward looking Wall Street players, OpenDoor decided to focus on delivering their core business proposition to their clients, and instead of building an in-house testing framework, they opted to deploy ETP Studio, a battle-tested toolset that met all their requirements for FIX protocol testing. At Esprow we believe that by partnering with us, clients get the best of both worlds: quick deployment of a premium technology for FIX testing, and an active development roadmap that approximates their own development team, keeping our products highly aligned to their needs.”
