Fee/rebate contingent order matching system and method
A specialized computer matching system programmed to match orders for financial instruments of any type; where orders are matched at a price equal to the best available price or within the best available prices in the market; where priority of matching orders is ranked by price; where orders at the same price may be further ranked based on other attributes; where orders may optionally specify that the order sender is willing to pay a fee to (or receive a rebate by) an Order Matching Entity (i.e., a fee/rebate contingency (FRC)); where an order's optional FRC must be met in order to match the order; and where an order which cannot be matched solely because its FRC rate prevents it from matching with another order temporarily yields priority—other than price priority—to other orders ranked below to permit those orders to be matched.
1. A method for matching using at least a contingent order matching system (COMS), the method comprising:
maintaining a plurality of stored electronic orders in a storage register in a first format that is compliant with the COMS, wherein the plurality of stored electronic orders are ranked according to a primary criteria and a secondary criteria;
receiving, over a network, incoming electronic orders in a second format that are only compliant for processing by an independent exchange system, at least a portion of the incoming electronic orders comprising contingency information; and
executing an order matching algorithm that converts the incoming electronic orders to the first format, thereby obviating a need for multiple exchange systems, including said independent exchange system, said executing comprising:
validating the incoming electronic orders, the validating comprising determining that the incoming electronic orders include requisite data for processing, and
matching the validated electronic orders with one or more stored orders of the plurality of stored electronic orders in the storage register, the matching based on a ranked priority which matches the one or more stored orders first by the primary criteria and then by the secondary criteria, except when at least one order of the one or more stored orders is determined to be unmatchable based on the contingency information, wherein if matched, the at least one order yields priority to lower ranked stored electronic orders in the storage register having a same primary criteria.
2. The method of claim 1 , wherein the COMS is part of one of an exchange and an over-the-counter market.
3. The method of claim 1 , wherein the receiving of the incoming electronic orders further comprises receiving electronic orders which cross one or more of the plurality of stored electronic orders in the storage register which may not immediately be matched, to form crossed electronic orders, and further comprising:
maintaining the crossed electronic orders in a crossed resting order book of the storage register for matching;
matching at least one among the crossed electronic orders held in the crossed resting order book with an incoming electronic order when possible; and
matching one or more of the crossed electronic orders held in the crossed resting order book with other electronic orders held in the crossed resting order book when possible.
4. The method of claim 1 , wherein the receiving of the incoming electronic orders further comprises receiving electronic orders which lock one or more of the plurality of stored electronic orders in the storage register which may not immediately be matched, to form locked electronic orders, and further comprising:
maintaining the locked electronic orders in a locked resting order book of the storage register for matching;
matching at least one of the locked electronic orders held in the locked resting order book with an incoming electronic order when possible; and
matching one or more among the locked electronic orders held in the locked resting order book with other electronic orders held in the locked resting order book when possible.
5. The method of claim 1 , further comprising:
giving priority in said matching to first matchable orders at a same price where a combined fee or rebate requirement of the first matchable orders totals at least at a predetermined minimum value if the first matchable orders were matched; and
yielding priority in said matching to second matchable orders at the same price where a combined fee or rebate requirement of the second matchable orders totals below the predetermined minimum value if the second matchable orders were matched.
6. The method of claim 1 , wherein said matching further comprises yielding the priority of the at least one order determined to be unmatchable to said lower ranked stored electronic orders for a predetermined time period.
7. The method of claim 1 , wherein the at least one order is determined to be unmatchable when contingency information of the at least one order and contingency information of the validated electronic orders, if matched, is less than a predetermined threshold.
