IMS student in Basel with an interest in performant C++. Currently learning by building a parser for Nasdaq's ITCH market-data feed.

Work

NASDAQ ITCH 5.0 Parser

Binary protocol parser for Nasdaq’s TotalView-ITCH market-data feed. Covers all 23 message types, built around doing as little work per message as possible. The first prototype works; a rewrite with proper throughput benchmarks is underway.
