@Richy_T: the pic represents the Bitstamp Orderbook over a time of 1 hour in 3D, right?
the walls below are then the (passive) Limit Orders in the Orderbook? on the left the Buy Limits? and on the right the Sell Limits? what about the (passive) Stop Orders? any chance to get them from the Orderbook?
Correct. I only have access to what is provided by the API. I don't see an option for that there.

^^ IMO, better you speak in terms of orders. (passive) Limit and Stop Orders of the one party of the deal (Buy or Sell). (active) Market orders of the other party of the deal (Sell or Buy).
Possibly. Bear in mind that the explanation is more for the uninitiated who might not be familiar with these terms. Those familiar with trading are likely to just "get it". It's basically the bottom part from bitcoinity.org made 3D.
