Use when building the sequencing layer of a co-located UDP multicast feed handler (CME MDP 3.0, MoldUDP64, Eurex T7 EMDI): A/B line arbitration, datagram re-sequencing, gap arbitration windows and venue retransmission escalation.
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
## When to Use Use this skill when writing or reviewing the **sequencing layer** of a feed handler that consumes redundant UDP multicast lines from an exchange. It covers the decisions that a handler gets wrong in ways that either corrupt a book silently or flood a venue with recovery requests: which copy of a duplicated datagram to keep, how long to wait before calling a missing packet lost, how many recovery requests one gap may generate, what to do when recovery comes back incomplete, and how to survive a sequence-number restart. The recovery model here is a three-tier hierarchy, and the ordering is the venue's, not a preference: 1. **A/B line arbitration.** CME sends every packet on both Feed A and Feed B and states the two feeds "should be used for arbitration"; Eurex replicates onto Service A and Service B and advises participants to join both. This tier costs nothing and repairs most loss. 2. **Retransmission**, where the venue offers one — and the transports differ. CME uses a TCP replay session; Nasdaq MoldUDP64 uses a **UDP unicast** Request Packet to a Re-request Server; **Eurex T7 has no retransmission service at all**. …

How to install
mdr add himanshuj16/algo-trading-skills/exchange-multicast-feed-handling@sha256:6c6314b4e6b16837The line at the top of this page pins the label v2.0.0, 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.
