Fidessa Promotes David Polen to Global Head of Electronic Execution

Subscribe to our newsletter

Fidessa has appointed David Polen as global head of electronic execution with responsibility for developing the company’s platform and electronic execution capabilities across global markets. Reporting to Mark Ames, global head of sell side services, Polen will deliver a range of managed solutions that will allow brokers to present their clients with intelligent and cost-effective global execution.

Ames comments: “It’s great to have David spearheading our efforts to strip out the complexity from global electronic execution. We aim to give brokers the breathing room to focus on creating a competitive advantage, while reducing costs and providing a homogenous trading experience.”

Polen adds: “Fidessa’s aim is to help brokers focus on trading ideas, rather than regulatory and technical intricacies. Navigating the current trading landscape is already complex and costly, with many subtleties associated with trading across asset classes and geographies. Brokers should be able to deliver innovation to their clients across this environment quickly.”

Prior to working at Fidessa, Polen was managing director at Lime Brokerage, where he was responsible for product management in the company’s systematic trading business line. His experience has focused largely on hosted product management in the equities and options markets, overseeing algorithms, market data and global order and execution management systems for cash equity and portfolio trading.
