Options chain

get_options_chain

Option chain for a US stock, ETF or index (SPX, NDX, RUT, VIX), delayed 15 minutes: strikes near spot with bid, ask, last, implied volatility, greeks, open interest and volume, plus per-expiry max pain, expected move, put/call ratios and totals. Defaults to the nearest 3 expirations within 10% of spot; narrow with expiration, type or strike_range_pct to save tokens.

Questions it answers

  • Which SPY strikes carry the most open interest this week?
  • What move is priced into Tesla options for earnings?
