Use when pricing physical commodity futures or designing roll strategies, linking spot to futures through financing, storage and insurance, extracting implied convenience yield and classifying contango against backwardation.
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 pricing physical commodity futures (Crude Oil `CL`, Natural Gas `NG`, Gold `GC`, Agriculture `ZC`) or designing term-structure roll strategies. The Cost of Carry model links spot prices ($S_0$) to futures prices ($F_T$) using financing costs ($r$), physical storage/insurance costs ($c$ proportional and/or $U$ per unit), and implied convenience yield ($y$). High convenience yield causes **Backwardation** ($F_T < S_0$), signaling physical inventory scarcity, whereas high storage costs relative to convenience yield lead to **Contango** ($F_T > S_0$).
## When NOT to Use
- **As an arbitrage signal generator on the cheap side of the curve.** For a consumption commodity the cost-of-carry relation is an *inequality*, $F_0 \le (S_0 + U)e^{(r+c)T}$, not an equality. Only the rich side is enforceable. A futures price below your fair-value estimate is a view about convenience yield, not a riskless trade, because you cannot generally borrow and sell short a physical commodity.

How to install
mdr add himanshuj16/algo-trading-skills/commodity-futures-storage-and-carry-cost-modeling@sha256:dcad17bed4ba6d96The 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.
