A system and methods for controlled market data delivery are described. According to one example embodiment, upon detecting a preset threshold of updates in a queue at a gateway, a predetermined number of market updates may be processed before any data is sent to a client terminal. According to one method, update types may be used to control how many updates are processed before any data is sent. Also, once the number of updates to be processed is set, a market update having a higher priority update type may be used to trigger a change in the number of market updates that was set for processing.
