Re: what is market depth

Market Depth is the outstanding buying and selling orders in the SEATS computer at any particular time for the shares of one class in a company at each of various price limits. (Renton's Dictionary of Stock Exchange & Investment Terms)

Here's an example from the NAB online trading site for QBE.

This just summarises the quantities at each price, but by selecting market detail, the individual orders at each price can be seen.
