Methods, systems and data structures are described for conducting synthetic continuous double auctions. A method includes participating in a synthetic continuous double auction having contingent bidding on a plurality of heterogeneous item auctions. A composite reverse auction, defined by a bid set including a first contingent bid on a first of the plurality of heterogeneous item auctions and a second contingent bid on a second of the plurality of heterogeneous item auctions, is ended when i) the first contingent bid from the bid set is recognized as a winning bid and substantially simultaneously ii) the second contingent bid from the bid set is withdrawn as a remaining bid. The bid set is visible to at least one member selected from the group of a) at least one first seller associated with the first of the plurality of heterogeneous item auctions, b) at least one second seller associated with the second of the plurality of heterogeneous item auctions, and c) buyers bidding on the first of the plurality of heterogeneous item auctions or the second of the plurality of heterogeneous item auctions.
