1. A system including:
a computing device having a processor and a memory storing instructions executable by the processor, including instructions executing the steps of:
receiving a plurality of market data update messages for a tradeable object from an electronic exchange, wherein each market data update message includes quantity available for the tradeable object at a plurality of price levels at a particular time, wherein the plurality of price levels includes a best bid price level and a best ask price level;
coalescing during a coalescing period, market data update messages of the plurality of market data update messages as they are received from the electronic exchange to generate coalesced market data, wherein the coalescing period represents a time interval during which coalescing will occur without sending updated market data to a trading device until the end of the time interval, wherein the coalescing period begins at a coalescing period start time and ends at a coalescing period end time;
identifying in response to receiving each market update message during the coalescing period, whether a price level transition has occurred, wherein a price level transition is identified when at least one of the best bid price level and the best ask price level in a currently received market update message has changed from a previously received market update message;
sending before the coalescing period end time, the coalesced market data to the trading device in response to identifying the price level transition has occurred; and
sending the coalesced market data to the trading device at the coalescing period end time when the price level transition is not identified to have occurred.
