Use when an exchange for physical has been negotiated but not yet submitted, validating the opposite-side leg structure, the physical-to-futures quantity correspondence and the basis before it reaches the venue.

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 on physical commodity desks, spot-futures basis books, index-arbitrage operations, and institutional block/EFRP workflows, at the point where an EFP has been negotiated but **not yet submitted** to the venue. An **Exchange for Physical (EFP)** — one of the EFRP transaction types governed by **CME Rule 538** and **ICE Futures U.S. Rule 4.06** — is a privately negotiated, simultaneous exchange of an exchange-traded futures position for a corresponding related cash position: physical commodity, spot FX, or a physical equity basket. The two legs are struck together, which removes leg-execution risk and lets the parties trade the basis directly.

This skill covers the three things that get an EFP rejected or investigated after the fact: a leg structure that is not actually an exchange, a quantity that does not correspond to the futures leg, and a bona fide determination that nobody recorded.

How to install

The exact contents, by fingerprint
mdr add himanshuj16/algo-trading-skills/exchange-for-physical-efp-transactions@sha256:debff3711b1b69fe

The 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.
