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.
TWS or IB Gateway must be running locally with API enabled:
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. If the retry succeeds, save to memory which account type worked (live/paper) and reuse it for all IB skill calls in this and future sessions — until the user explicitly asks for the other account. If both ports fail, ask the user to verify that TWS or IB Gateway is running with API access enabled.
First, get available expiration dates:
uv run python scripts/options.py SYMBOL --expiries
Then fetch the chain for a specific expiry:
uv run python scripts/options.py SYMBOL --expiry YYYYMMDD
SYMBOL - Ticker symbol. Equity/ETF (e.g., AAPL, SPY, TSLA) or futures root (e.g., NQ, ES, CL, GC) — asset type is auto-detected via IB.--sec-type {stk,fut} - Force the asset type. Default: auto-detect (stock-first). Use fut for ambiguous roots like ES/CL when you mean the future.--expiries - List available expiration dates only--expiry YYYYMMDD - Fetch chain for specific date (IB format: YYYYMMDD, no dashes)--port - IB port (default: 7497 for paper trading)test cases passed, vs 6 / 13 without
