Pre-arranged crosses within the same house is quite different than the previous system of registering a large volume of shares on either the Bid or Ask side at "all or nothing".

The showing of the pre-arranged crosses is simply a matter of recording same on the exchange. In most cases it is some form of book keeping and balancing of accounts.

It is my understanding that you can no longer for example register 2 million shares at 1 cent above the current ask at "all or nothing" as it presents a barrier that is not real.
