Abstract: Disclosed embodiments provide a computing system configured to match a set of transactions associated with an online trading system. The computing system includes a memory that includes a client service engine, a price update event engine, and a match processing engine. The computing system further includes a processor coupled to the memory. When executing the client service engine, the processor is configured to receive, from one or more client devices, a plurality of order requests during a first interval of configurable duration. When executing the price update event engine, the processor is configured to set a plurality of mid-rate prices corresponding to the first interval. When executing the match processing engine, the processor is configured to determine that the first interval has expired, and in response, match a first order request included in the plurality of order requests with a second order request included in the plurality of order requests.
