What it does
- Takes spot, strike, expiry (or DTE) and call/put and returns delta, gamma, theta, vega and rho.
- If you pass the option's market price (
--price), it back-solves implied volatility with Newton-Raphson. - Outputs structured JSON and anchors all time calculations to the America/New_York timezone.
- Claude then explains what each Greek means for your specific position.
Who it's for
- Retail options traders who want a fast read on position sensitivities.
- Traders extracting IV from market quotes to judge whether an option is rich or cheap.
- Students and analysts automating Black-Scholes math for coursework or research.
Usage examples
- "Get IV and Greeks for a 600 call, spot 630, expiring 2026-05-15, trading at 72.64."
- "How much does theta decay per day on a 30-DTE 600 call with spot 630 priced at 40?"
- "Show how the Greeks of that same contract look as of 2026-03-01."
