Firms will now have sub-one millisecond access to a number of market data and execution venues including Turquoise, Chi-X Europe and BATS Europe.

Radianz Ultra Access provides a high speed, fully resilient service that provides ultra low latency connectivity between exchanges and brokers. The TABB Group estimates that if an agency-broker's electronic trading platform is relying on a service five milliseconds behind the competition, it could cost the firm up to $4 million. The research also estimates that a ten millisecond differential from the competition could potentially result in a 10% drop in revenues for a firm. BT's low latency offering ensures very low variability in latency and gives customers assurance of 100% availability, which is also critical in today's market.

Andy Nicholson, VP, Global Banking & Financial Markets at BT Global Services said: "Current market demand and industry trends in low latency have raised the bar across the industry, and connectivity speed is now, more than ever, a critical factor for all major market centres across the globe. BT is confident in its ability to enhance the electronic trading environment through Radianz Ultra Access and provide users in London with a necessary competitive advantage."

London is the first city in Europe to offer the service and BT will look to roll out Radianz Ultra Access in other key European centres later this year. Radianz Ultra Access is part of BT's low latency portfolio, which also includes Radianz Proximity Solution and Low Latency Management services powered by Corvil. Radianz Proximity Solution is available in all major market centres and allows BT customers to co-locate trading engines near execution venues to reduce market data and trading latency. Low Latency Management services powered by Corvil is a professional services capability that provides network latency management for the global capital markets via a strategic partnership with Corvil.
