Interactive Data's ComStock Launches PlusFeed,

the real-time datafeed for financial applications

New York: 15 November 2005 - ComStock Inc., an Interactive Data company (NYSE: IDC) and a leading provider of real-time global market data, today launched PlusFeed, its rebranded real-time datafeed for financial applications. ComStock has rebranded the datafeed to reflect the extensive enhancements made over the past two and half years. PlusFeed was previously known as XpressFeed.

“We wanted to highlight the vast improvements made to the datafeed since the acquisition of ComStock by Interactive Data almost three years ago,” said Mark Hepsworth, president of ComStock. “The changes have been so significant that the feed today bears little resemblance to the feed of three years ago. Interactive Data has invested heavily in ComStock since the acquisition, and all aspects of the datafeed – especially the ticker plant, distribution network and data content – have been substantially upgraded. The new name, PlusFeed, demonstrates how much more comprehensive the feed is today.”

Over the last three years Interactive Data has invested heavily in state-of-the-art technology and redundant facilities to deliver high quality, low latency data. New ticker plants have been commissioned specifically designed to handle the rapidly growing market data volumes.

Interactive Data has also made considerable investment in its distribution networks. The February 2005 launch of ComStock’s cutting edge distribution network, IP4, which has a capacity to deliver up to 42Mbps of data, represents a sevenfold increase over the 6Mbps limit of the preceding IP3 network. ComStock has additionally introduced technology that allows clients to create custom feeds limiting the bandwidth for the specific data sets required.

On the client side, ComStock has introduced enhanced hardware and software running 64 bit applications that are capable of processing much larger volumes of data with minimal latency. The client side infrastructure also allows data processing to be distributed across multiple client servers. In addition, ComStock has introduced a new protocol and C++ API to simplify and expedite the integration of its datafeed into client applications and minimize ongoing feed maintenance.

ComStock has been aggressively adding an extensive list of new data sources to the feed, both exchange-based and contributed. PlusFeed now carries over 350 global sources of data, across all asset classes, with coverage of more than 2.3 million instruments.
