London : 10 September 2008
Interactive Data Corporation (NYSE: IDC), a leading provider of financial market data, analytics and related services, today announced that its Real-Time Services business has made data from the Turquoise multilateral trading facility (MTF) available via PlusFeed.  PlusFeed is Interactive Data’s consolidated high-quality, low latency digital datafeed that powers algorithmic and electronic trading applications. 

Data from the Turquoise MTF, whose members include the largest banks and brokers active in European trading, as well as specialist trading firms and institutions, has been in production on PlusFeed since 15 August 2008 and is available to Interactive Data’s PlusFeed clients from the commencement of live trading.  Since 29 August the Turquoise platform has stepped up its production capabilities and now trades in over 1,250 stocks across 13 European markets ahead of its public launch later in September.

Yann L’Huillier, chief technology officer of Turquoise, said: "We are pleased that low-latency data provider Interactive Data is making Turquoise data available to its clients, as we see it as essential that financial institutions are able to access the data we produce as quickly as possible.” 

David Hann, general manager, EMEA, Interactive Data Real-Time Services, commented: "Adding Turquoise data to PlusFeed is an important step forward for us.  

Since the Markets in Financial Instruments Directive (MiFID) was implemented on 1 November 2007, Interactive Data has seen significant increases in the volume of trades and in the number of instruments on the new data sources available via PlusFeed.  And the numbers indicate that this growth is continuing.”  

Interactive Data’s Managed Solutions business will also carry Turquoise data on Market Data Gateway as part of a new ECN package.  Market Data Gateway is a fast and flexible open platform enabling the aggregation and normalisation of financial market data from various sources.  Interactive Data’s PrimePortal and PrimeDeveloper clients will have the option of subscribing to the new ECN package, while PrimeTerminal clients will receive the data as part of their contributor data package.
