Today we are delighted to announce more Real-Time ECN information. We have created a new page that has real-time streaming prices for the bid, bid size, ask, ask size and the top of the book.
The top of the book is commonly referred to as Level 2 data and this features the 5 highest bid prices and size as well as the 5 lowest ask prices and size on BATS Trading.
Check out our new Real-Time ECN page at http://finance.yahoo.com/q/ecn?s=YHOO, and watch your favorite stock in real-time. Let us know what you think and stayed tuned for further integration on Yahoo Finance.
