HAYWARD, Calif. -- eSignal, a division of Interactive Data Corporation (NYSE: IDC) and a leading provider of streaming, real-time financial market data, news, analytics and decision-support tools for professional and individual traders, today announced that eSignal's portal sites, Quote.com([R]) and RagingBull.com, now offer NYSE Euronext and NASDAQ-listed stocks' real-time last sale and quote market data from BATS Trading (BATS), the third-largest U.S. equity market.

"eSignal has deployed our real-time feed on its financial portal sites and soon will have our full depth of book, including all bids and asks at all price levels," said BATS Chief Executive Joe Ratterman. "We are excited to partner with eSignal, facilitating an even broader delivery of key stock market information to millions of Internet users."

Data feeds supplied by other market centers typically include only last sale information, and they often carry a significant price tag as well. The BATS data feed is provided free of charge to everyone visiting the Quote.com and RagingBull.com sites, and the information provided by BATS includes not only last sale, but soon will also include full depth of book data. These additional real-time elements are vital to providing visitors to financial web sites a more complete picture of the true reference price for securities.

"We are delighted to offer free real-time market data to everyone visiting our Quote.com and RagingBull websites," said Chuck Thompson, president of eSignal. "By teaming with BATS to provide our visitors with a broader set of free, real-time trading information, we can further differentiate our financial information web sites from others in the trading marketplace."

BATS recently received approval from the US Securities and Exchange Commission to become a registered national securities exchange and currently accounts for more than 10 percent of the total matched volume traded in the U.S. eSignal will also display the full BATS order book, as well as BATS' European Markets division when its trading platform goes live this fall.
