Use when a parent TWAP, VWAP or POV schedule's instrument stops trading continuously on a pause or halt; issues child cancels and tracks them to venue acknowledgement rather than assuming they landed.
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 in institutional execution algorithms (TWAP, VWAP, POV, Implementation Shortfall), Smart Order Routers, and automated execution risk engines that must survive their instrument going non-continuous mid-schedule. Two facts make the naive implementation of this dangerous, and both are why the engine is shaped the way it is: - **Resting orders do not disappear when trading stops.** In US equities they persist through a LULD pause and are *eligible interest for the reopening auction* — so an algo with stale limit orders on the book is quoting into the single most volatile print of the day. Cboe additionally cancels-or-preserves resting orders based on a **port-level configuration setting**, so what happens to your book is a function of how your session was provisioned, not something you can assume. …

How to install
mdr add himanshuj16/algo-trading-skills/execution-algo-behavior-under-halted-instrument@sha256:3ff338fb541f99d2The 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.
