Achieve better trade performance by viewing all the buy and sell orders in NASDAQ for securities listed on NASDAQ, the NYSE and the Amex. Powered by NASDAQ TotalView, BookViewer is the standard-setting data product for the serious trader, allowing users to see much more depth than the typical Level 2 data offers. The data – which is comprised of all order activity in the NASDAQ system - can be aggregated either by price level or by MPID. Orders received into NASDAQ’s book are immediately visible on BookViewer, regardless of the order’s size and the identity of the party placing the order.
