/**
 * One past session's bars across one expiration, by strike: open, high, low, close, volume, VWAP and trade count for every contract, active or expired, with `traded: false` for a contract that did not trade that session. When the expiration holds more contracts than `limit`, the strikes nearest that session's stock close are returned (`truncated` flags the cut). Narrow with `minStrike`/`maxStrike` and `type` (call/put). History begins in early 2024. Plus can read a session 30 minutes after the stock close; Pro can read the current session, with `final: false` on a read that began before it 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.
