BT's Radianz Ultra Access is a high-speed, fully-resilient service providing ultra-low-latency connectivity between investment banks, brokers and investment managers and the exchanges and MTFs on which they trade. It can deliver sub-millisecond access to all London-based users of Chi-X Europe.

In order to maintain its position as the market-leading MTF for trading pan-European equities, Chi-X Europe must ensure that the round-trip latency between its users' trading systems and the Chi-X Europe platform is minimal. BT's Radianz Ultra Access will help Chi-X Europe to deliver this.

Hirander Misra, Chief Operating Officer, Chi-X Europe, said: "Chi-X Europe's matching engine is rated as super-fast for matching trades with an average internal latency of 350 microseconds. In order to take advantage of this it is vital that our participants have the lowest-latency inbound connectivity possible while also having sufficient spare capacity to deal with daily peaks in trading activity. BT's Radianz Ultra Access will help us to maintain our market-leading position by providing participants with ultra-fast fibre access to trade on the Chi-X visible order book and the Chi-DeltaTM non-displayed order book as well as to utilise our Chi-VisionTM smart liquidity consolidation service."

Andy Nicholson, VP, Global Banking and Financial Markets at BT, said: "It is critical that market participants can connect to MTFs and exchanges at sub-millisecond speed. Not only will Radianz Ultra Access enable Chi-X Europe to deliver this ultra-high-speed connectivity to its users, but it will also improve efficiency and liquidity in the market."

The implementation of Radianz Ultra Access to Chi-X Europe extends the existing relationship between the two companies. BT is already a leading provider of network services to many participants of Chi-X Europe in the UK and Continental Europe.
