Option Greeks

Calculate Greeks for options using Black-Scholes model. Computes IV from market price via Newton-Raphson.

Instructions

Note: If uv is not installed or pyproject.toml is not found, replace uv run python with python in all commands below.

uv run python scripts/greeks.py --spot SPOT --strike STRIKE --type call|put [--expiry YYYY-MM-DD | --dte DTE] [--price PRICE] [--date YYYY-MM-DD] [--vol VOL] [--rate RATE]

Arguments

  • --spot - Underlying spot price (required)
  • --strike - Option strike price (required)
  • --type - Option type: call or put (required)
  • --expiry - Expiration date YYYY-MM-DD (use this OR --dte)
  • --dte - Days to expiration (alternative to --expiry)
  • --date - Calculate as of this date instead of today (YYYY-MM-DD)
  • --price - Option market price (for IV calculation)
  • --vol - Override volatility as decimal (e.g., 0.30 for 30%)
  • --rate - Risk-free rate (default: 0.05)

Output

  • spot - Underlying spot price
  • strike - Strike price
  • days_to_expiry - Days until expiration
  • iv - Implied volatility (calculated from market price)
  • greeks - delta, gamma, theta, vega, rho

uv run python scripts/greeks.py --spot 630 --strike 600 --expiry 2026-05-15 --type call --price 72.64

# With DTE directly
uv run python scripts/greeks.py --spot 630 --strike 600 --dte 30 --type call --price 40

# As of a future date
uv run python scripts/greeks.py --spot 630 --strike 600 --expiry 2026-05-15 --date 2026-03-01 --type call --price 50

Optional --rr-gate and --time-gate add red→red and bar-timing confirmation. Supports cash-settled indices (SPX, NDX, RUT, VIX) and any optionable stock/ETF.
