/**
 * Past bars for one option contract by its OCC symbol, active or expired, newest first: open, high, low, close, volume, VWAP and trade count. A period without trades has no bar, so a gap means no trades. `timeframe` is day (default, last 90 days), hour (last 7 days) or minute (last 4 days); `startDate` and `endDate` set another window. History begins in early 2024. Plus receives bars 15 minutes after they end; Pro receives them as they form, with `final: false` on a bar read before its period ended. The Free plan covers end-of-day data only and receives 403. Open interest, greeks and bid/ask have no history here; implied volatility history is `/options/volatility`. US listings only.
