Abstract
Presently disclosed are systems and methods for targeted exchange emulation. In an embodiment, an output-feed profile that specifies a ticker-symbol subset is maintained at a market data processing device (MDPD). An input feed of order-book updates to respective ticker symbols is received at the MDPD from an upstream device. An output feed is generated at the MDPD at least in part by filtering the received input feed down to order-book updates to the ticker-symbol subset and generating output-feed messages that convey the remaining order-book updates. The generated output feed (including the generated output-feed messages) is transmitted from the MDPD to a downstream device. Cached copies of at least the order-book updates from the input feed that correspond with output-feed messages in the output feed are stored at the MDPD. A gap-fill service for the output feed is provided from the MDPD to the downstream device using the cached copies.
