/**
 * The trade tape for one option contract by its OCC symbol, active or expired, newest first: time, price, size, exchange and condition. A cancelled print stays in the tape with `cancelled: true`, so read volume from the bars rather than a sum of prints. Defaults to the last 4 days; `startDate` and `endDate` set another window, and history begins in early 2024. When `truncated` is true, pass the oldest row's `time` as `endTime` to continue. Plus receives trades 15 minutes after they print. The Free plan covers end-of-day data only and receives 403. US listings only.
