Systems and methods for generating customized filtered-and-partitioned market-data feeds

A market-data-processing device (MDPD) comprising:

• a plurality of external data ports including a first external data port and a second external data port, wherein the MDPD is configured to receive, from an upstream device and via the first external data port, an input feed of order-book updates to respective ticker symbols in a plurality of ticker symbols;
• and
• a programmable logic circuit (PLC) that is configured to:
• maintain an output-feed profile that specifies a ticker-symbol subset and a ticker-symbol-based feed-partitioning scheme, wherein the ticker-symbol subset is one or more ticker symbols from among the plurality of ticker symbols;
• and
• generate a customized market-data output feed according to the maintained output-feed profile at least in part by:
• filtering the received input feed down to a filtered feed of the order-book updates to respective ticker symbols in the ticker-symbol subset;
• and
• partitioning the filtered feed according to the ticker-symbol-based feed-partitioning scheme,
• wherein the MDPD is further configured to transmit the customized market-data output feed via the second external data port to a downstream device.
