At a glance

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.

  • User asks about options using IBKR data
  • SKILL.md covers IB Connection, Instructions, Arguments and Output, plus 2 more sections
  • Runs Python scripts from its folder; calls uv
  • Futures options (NQ/ES/CL/GC...)

What it does

Ib Option Chain is an agent skill from staskh/trading_skills. 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.

Its SKILL.md is about 870 tokens, which your agent loads only when the skill is triggered. The skill folder holds 2 other files, including scripts (for example `scripts/options.py`).

It sits in Business, Finance & HR, covering Stock and market analysis. The repository describes itself as: Claude powered advisor system for option traders. The licence is MIT.

When your agent uses it

  • User asks about options using IBKR data
  • Futures options (NQ/ES/CL/GC...)
  • Needs real-time option quotes from their broker

Example prompts

  • “/ib-option-chain”

Requirements

  • Python 3

What it can do on your machine

Read from SKILL.md and the folder at commit b71a74f. It shows what the files ask for, not the result of running them.

  • Tool permissions

    Pre-approves nothing: there is no allowed-tools line, so your agent's usual permission prompts apply.

    From allowed-tools in the SKILL.md frontmatter.

  • Runs code

    Ships 1 file in scripts/ (Python), which the agent can run.

    Shell commands in SKILL.md call:

    • uv

    From the folder's file list and the shell code blocks in SKILL.md.

  • Network

    No URLs in SKILL.md. Its commands use uv, which can reach the network depending on how they are called.

    From URLs in SKILL.md, links to its own repository left out.

  • Credentials

    Names no API keys, tokens, secrets or passwords.

    From names ending in _API_KEY, _TOKEN, _SECRET, _KEY or _PASSWORD in SKILL.md.

Context cost

Ib Option Chain loads about 873 tokens when it runs. Until then it costs about 95 tokens; SKILL.md has 418 words of instructions outside code blocks.

Always · name and description, kept in context so the agent knows when to use it
~95
When it runs · the whole SKILL.md, loaded when a task matches
~873

Estimates: characters ÷ 4, the usual rule of thumb; real counts depend on the model's tokenizer. Scripts and assets cost tokens only if the agent reads them.

Safety

Auto-check: notes

The automated check noted patterns worth knowing about, such as sudo or a known installer.

  • NoteMentions a .env fileSKILL.md:22
    lt-in default. Set it in the shell or a `.env` file.

Automated static check — not a guarantee. Review scripts before installing. It scans the text of SKILL.md for risky patterns (piping downloads into a shell, reading credential files, hidden Unicode, destructive commands); the scripts in this folder are not scanned.

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. 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.

Instructions

First, get available expiration dates:

bash
uv run python scripts/options.py SYMBOL --expiries

Then fetch the chain for a specific expiry:

bash
uv run python scripts/options.py SYMBOL --expiry YYYYMMDD
Show full SKILL.md (188 more words)Show less

Arguments

  • 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)

Output

Returns JSON with:

  • calls - Array of call options with strike, bid, ask, lastPrice, volume, openInterest, impliedVolatility, greeks (delta/gamma/theta/vega/iv from IB model), and multiplier (futures only)
  • puts - Array of put options with same fields
  • underlying_price - Current underlying price for reference (stock/ETF price or continuous-future price)
  • asset_type - "stock" or "future"
  • source - "ibkr"

For futures, only expiries up to the front continuous-future's expiry are returned; longer-dated FOPs require the next quarter's future. Futures quote nearly 24h on Globex, so Greeks populate pre-market.

Present data as a table. Highlight high volume strikes and notable IV levels.

Dependencies

  • ib-async

Timezone

All timestamps and time-based calculations must use the America/New_York timezone. All JSON output must include generated_at (NY time string) and data_delay fields.
