Use when decoding fixed-layout binary market data by byte offset (NASDAQ ITCH, CME MDP 3.0 SBE, Eurex T7 EMDI): frame validation, message-type dispatch, fixed-point tick prices and zero-copy buffer walking that fails loud.
Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.
What the file says
# Binary Protocol Parsing for Low Latency Feeds ## Context & Rationale Exchanges distribute market data as raw binary packets over UDP multicast. Text and schema-driven serialization (JSON, XML, Protocol Buffers) costs orders of magnitude more than a fixed-layout binary decode, so feed handlers read network bytes directly into application structs using precompiled layouts. The dominant production risk in this code is not slowness — it is a **silent misparse**. A frame decoded against the wrong layout does not raise; it returns a plausible message with a real-looking symbol, size, and price, which then corrupts order book state and feeds bad inputs to alpha models. Every decode path in this skill therefore validates before it returns. ## Core Concepts - **Struct Unpacking**: Converting contiguous bytes into primitives using a precompiled `struct.Struct`, with endianness stated explicitly. - **Offset-Based Buffer Walking**: Passing `(buffer, offset)` into the decoder rather than slicing per message. Slicing `bytes` copies; a `memoryview` plus an offset does not. - **Fixed-Point Scaling**: Exchanges transmit prices as scaled integers (ITCH …

How to install
mdr add himanshuj16/algo-trading-skills/binary-protocol-parsing-for-low-latency-feeds@sha256:438517e4b8f1aef6The line at the top of this page pins the label v1.1.0, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
