 Have you ever wondered where the big boys are buying and selling the market? Well the truth is, they purposely hide this information from you using iceberg orders. This special type of limit order splits up a large order and only displays a piece of it in the order book, allowing professionals to execute massive trades in secret. All you see is the tip of the iceberg. That is, until now, using MBO data and some clever engineering. Bookmap has turned on the x-ray goggles to show you exactly where the large institutions and banks are playing.
