An assignment exchange and auction system comprises a server, a network, a plurality of trader systems and a data store unit. The server performs the auction or exchange, creates and receives assignment messages, and retrieves and stores data sets to and from the data storage unit. The server processes bids and bid groups cooperates with the allocation system to determine an allocation of lots that maximizes a total money value for a plurality of bid groups subject to one or more constraints. The server also cooperates with the plurality of trader systems to present user interfaces for entering bids and bid groups, entering constraints for the bids and bid groups, and show the results of an auction or exchange. The present invention also includes a method for assigning, pricing or exchanging multiple types of lots comprising the steps of: receiving a first bid group from a first bidder; receiving a constraint for the first bid group; receiving a second bid group from a second bidder, determining an allocation of lots that awards bids to the first bidder and the second bidder, wherein the allocation maximizes, subject to the received constraint, a first total money value of awarded bids to the first bidder and a second total money value of awarded bids the second bidder; and notifying the first bidder and the second bidder of the allocation.
