Use when redundant order-entry sessions to a venue must fail over safely, confirming liveness first, fencing the failing session against split-brain and resolving the standby's own sequence numbers.
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 a trading system holds redundant order-entry sessions to a venue (Active-Standby FIX sessions, an ETI session pair, an iLink fault-tolerant group) and needs a defensible answer to three questions at the moment the active session degrades: *should we fail over*, *what sequence number does the standby log on with*, and *what happens to the orders we sent but never got acknowledged*. It is a decision engine and a test harness for failover drills — it performs no I/O, opens no sockets, and sends no orders. The dangerous part of a gateway failover is not the switch. It is the set of orders in flight when the session died: an unacknowledged `PENDING_NEW` may be resting at the venue, may have filled, or may never have arrived, and the three are indistinguishable from the client side. This engine refuses to resend any of them until the venue says which. ## When NOT to Use - **As a FIX/ETI session implementation.** It decides; your session layer connects, logs on, cancels and resends. It cannot detect a dead socket — you sample health and pass it in. …

How to install
mdr add himanshuj16/algo-trading-skills/exchange-gateway-redundancy-and-failover-testing@sha256:ca9b15e3d7e835c7The 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.
