Embodiment Construction

[0013] In FIG. 1, a general view of several interconnected exchanges is shown. Thus, the exchanges 101, 103 and 105 are all interconnected by bi-directional communication paths. The communication paths interconnecting the different exchanges 101, 103 and 105, respectively can be wireless or wireline communication paths, which ever turns out to be the most suitable for the particular case.

[0014] In FIG. 2, a flow chart illustrating the steps carried out in a procedure when matching orders in the exchange system shown in FIG. 1 is shown. In the example below it is assumed that a buying order is received in the exchange 101, which is an automated exchange. The other exchanges can be open outcry exchanges or can be automated exchanges too.

[0015] Thus, first in a step 201 the buying order is received. Next in a step 203 the best selling order in the order book is checked. Thereupon, the best selling orders in the other automated exchanges, i.e. the exchanges 103 and 105 in this example, ...
