First and Only CEP Platform to Connect to Alpha Trading System

LEXINGTON, MA — March 9, 2009 — StreamBase Systems, a leading provider of complex event processing (CEP) technology, announced today that its software has been extended to connect to the trading platform recently launched by Alpha ATS L.P. (“Alpha”). 

The launch of the Alpha trading system provides an innovative new venue for trading Canadian listed equities, and the StreamBase connectivity, released as integrated CEP platform adapters, allows firms to gain first-mover advantage by providing “drop-in” connectivity. Alpha connectivity allows CEP-based applications such as Smart Order Routing, algorithmic trading, and real-time market data analytics to connect to the markets independently or simultaneously. 

“Our first move to provide connectivity to Alpha demonstrates StreamBase’s commitment to help our customers get to market quickly,” said Mark Palmer, CEO of StreamBase. “By providing a low-latency, high throughput offering, we have extended our platform so firms can not only get to market quickly, but can do so with the kind of scalable, multi-threaded capability that they expect from the industry’s fastest CEP platform so that they may gain instant insight into the market.”

Jos Schmitt, CEO at Alpha commented, “The provision of a low latency solution to the integration of our trading platform with our customers’ electronic trading systems is essential to ensure our success; we welcome the news that StreamBase is supporting access to Alpha.”
