Abstract: The disclosed embodiments relate to systems and methods which match/allocate an incoming order to trade with “resting,” i.e. previously received but not yet matched, orders, recognizing that the algorithm or rules by which the incoming order is matched may affect the operation of the market for the financial product being traded. In particular, the disclosed embodiments relate to an adaptive match engine which draws upon different matching algorithms, e.g. the rules which dictate how a given order should be allocated among qualifying resting orders, depending upon market conditions, to improve the operation of the market. Thereby, by conditionally switching among matching algorithms within the same financial product, as will be described, the disclosed match engine automatically adapts to the changing market conditions of a financial product, e.g. a limited life product, in a non-preferential manner, maintaining fair order allocation while improving market liquidity, e.g., over the life of the product.
