An order matching method matches orders to buy and sell (and execute cross transactions in) financial instruments by matching orders at a price equal to the best available bid or ask price or within best available bid and ask prices in the market; where the priority of matching is by price; where orders may optionally specify that the order sender is willing to pay a fee to (or be paid a rebate by) the Order Matching Entity which operates the matching system (a fee/rebate contingency-quantified by a fee/rebate contingency rate (FRC rate); where an order's fee/rebate contingency must be met 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 the yielding order to permit those orders to be matched, if possible.
