Fidessa Extends Trading Services to Canada on Platform Equinix

Toronto data center chosen to support Fidessa expansion into Canada

REDWOOD CITY, Calif. — May 2, 2011 — Equinix, Inc. (Nasdaq: EQIX), a provider of global data center services, today announced that Fidessa Canada corporation, part of Fidessa group plc (LSE: FDSA) and provider of high-performance trading, investment management and information solutions for the world’s financial community, will host its Canadian trading platform in Equinix’s Toronto TR1 International Business Exchange™ (IBX®) data center. Fidessa is already present in several Equinix IBX data centers, including London and Singapore.

Fidessa is leveraging Platform Equinix to expand its global footprint into Canada. Fidessa’s requirement in Canada involved access to a wide range of networks to deliver trade execution, market data and connectivity solutions for high frequency, cross-border and multiple-asset class trading.

Martin Hakker, managing director at Fidessa Canada, said: “Canada is experiencing many changes in the form of liquidity fragmentation, new market regulations and product innovation. As part of our global strategy, we sought a data center provider close to the financial hub in Canada and one with access to a dense network of service providers. Platform Equinix fit the bill with its vast ecosystem of exchanges, market data providers and financial institutions.”

Fidessa’s Canadian trading platform provides access to all of the Canadian trading venues, including the Toronto Stock Exchange. It offers execution services and market data for equities, equity options, futures, derivatives and bonds. Customers can choose to use the platform for trade execution, market data and connectivity either separately or together.

John Knuff, general manager, global financial services at Equinix, said: “Fidessa’s commitment to providing customers with access to the best possible trading products and services will be well supported by our data center in Toronto. Fidessa is leveraging the benefits of Platform Equinix including its global footprint and high density of networks in key financial markets.”

The partnership with Equinix represents Fidessa’s second co-location deal in Toronto this year. On February 8, TMX Group and Fidessa announced that Fidessa would host its trading solutions onsite at TMX Group’s co-location facility. Fidessa, along with other co-located clients, receives the benefits of direct high-speed access to Toronto Stock Exchange, TSX Venture Exchange and Montreal Exchange trading engines and market data feeds.
