This agreement will provide a direct link between the LongView Trading Order Management System (OMS) and the BIDS ATS, giving users the ability to anonymously trade large blocks of US equities on BIDS Trading.

"We are very pleased about adding BIDS Trading to the LongView Liquidity Alliance Partnership," said Gregg Drumma, Vice President of STP Product Development, Linedata Services. "Our advanced integration provides an effective synchronization between the LongView Trading OMS and the BIDS ATS. In a fast growing market where alternative trading is increasingly sought after, we are committed to providing our clients with the most reliable technology paired with cutting edge solutions for trade execution."

Interest in BIDS Trading from the institutional investment community continues to grow. Since its formal launch in early 2007, the BIDS ATS has executed more than 1.9 billion shares*.

"Providing connectivity to LongView Trading's premier OMS will give a new, broad base of market participants the ability to execute trades on BIDS Trading's open, flexible ATS," said Tim Mahoney, Chief Executive Officer of BIDS Trading. "With additional connections to more and more electronic trading platforms, we come closer to achieving our goal of offering buy- and sell-side firms access to superior execution and liquidity."

The BIDS ATS is accessible to both buy-side and sell-side firms that want to trade large blocks through continuous order matching and trade negotiation. Use of the BIDS ATS as a block trading service is not exclusive or subject to volume commitment and each participant may continue to use any ATS, ECN or exchange service that supports the trading needs of its customer base.

The BIDS ATS allows traders to control their level of information disclosure. Market participants can choose to auto-execute their order or negotiate, they can set their minimum block size to help protect their order, and they can filter counterparties based on past tradiing behavior.
