Get option chain data from Interactive Brokers for equities, ETFs, and futures (FOP), including calls and puts with strikes, bids, asks, volume, implied volatility, and model Greeks. Use when user asks about options using IBKR data, futures options (NQ/ES/CL/GC...), or needs real-time option quotes from their broker. Requires TWS or IB Gateway running locally.
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
# IB Option Chain Fetch option chain data from Interactive Brokers for a specific expiration date. Handles **equities/ETFs** (Stock/OPT) and **futures options** (FOP). The asset type and exchange are resolved from **IB contract details** (no hardcoded symbol table): auto-detect tries a SMART stock first and falls back to a future when no stock exists (so `NQ`, `GC`, `RTY` resolve as futures, while `AAPL` resolves as a stock even though it has an obscure single-stock future). Tickers that are **both** a stock and a futures root (e.g. `ES`=Eversource, `CL`=Colgate) default to the equity — pass `--sec-type fut` to force the future. ## IB Connection TWS or IB Gateway must be running locally with API enabled: - **Paper trading** — port 7497 - **Live trading** — port 7496 - **`IB_PORT` env var** — default port when `--port` is omitted (e.g. `IB_PORT=4001` for a Gateway container). Precedence: `--port` flag > `IB_PORT` > built-in default. Set it in the shell or a `.env` file. **Port fallback:** If the configured port fails, automatically retry on the other port. …

How to install
mdr add staskh/trading_skills/ib-option-chain@sha256:43e4b6f94056ce88The line at the top of this page pins the label git:20260716.c0c554f, 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.
