Lupien further discloses that traders input as orders a
satisfaction density profile (SDP) and maximum size limit which
characterizes the trader’s degree of satisfaction to trade at any
and all prices and sizes up to the size limit (col. 3, lines 44-
53). Lupien further discloses that the SDP is a two dimensional
grid with one dimension being price and the other dimension being
the size of the transaction (col. 3, lines 54-58). Each trader
can input one or more profiles (col. 4, lines 1 and 2). From the
disclosure that a trader can input one or more SDPs, we find that
an SDP can represent a single trading interest. It is further
disclosed that once the SDP is complete, it is transmitted to the
controller which anonymously matches buy and sell orders (col. 4,
lines 6-9).
Assume a batch process where multiple traders enter SDPs
that represent buy or sell orders for a particular stock. Upon
transmission of the SDPs to the central matching controller
(CMC), the CMC will cause buy profiles to be stored in a buy
profile database and will cause sell profiles to be stored in a
sell database. The CMC will then calculate, for each buy/sell
pair, a mutual satisfaction cross product. The values of the
cross products are ranked in order, and the matching continues
down the ranked list (col. 4, lines 10-26).
