Choose the right protocol
Compare message meaning, session recovery, transport, and encoding before interpreting latency benchmarks.
READING COLLECTION / TOPIC
PROTOCOLS.
Compare interfaces by the operations and recovery behavior they support. Message meaning, session management, transport, and encoding are distinct layers that should not be collapsed into a single speed ranking.
How to use this collection
The protocol field guide provides a requirements-first evaluation process. Pair it with the API architecture overview and market-data collection to decide what an adapter must preserve. A candidate interface is ready for review when required features are supported by evidence, unsupported features are identified, and unknowns remain visible rather than becoming assumptions.
Connect these readings with the HFT API blueprint, the market tracks, and the technical glossary. Each full article links to a primary reference for its documented example. Consult current provider specifications before applying the ideas to an actual integration.
