Combinatorial double auctions
Developing a capacity to process combined-value orders
Combinatorial Orders (CO) are requests to purchase or sell combinations of securities (e.g., buy ANZ AND BHP at a combined price of $70 or less but not separately; sell ANZ OR BHP at a price of $30 or more but not both). They are also referred to as "combined-value orders" or "package orders." We are developing the capacity to process COs in the standard electronic financial-markets exchange mechanism, namely, the open-book system (as used by, among others, ASX, Euronext and others).
