Current logical schema for lake.intraday_options_quotes

Coverage and timing

Raw OPRA NBBO at (ticker, minute) grain, whether or not a trade printed — use for spread studies, where trade-grain sources under-sample wide quotes. Requires a literal `date` range and a `ticker` filter. ~1 GiB and ~289M rows per day, one object per day, so the range decides what is read: e.g. `date BETWEEN DATE '2026-09-15' AND DATE '2026-09-19'`; unbounded queries are rejected. Coverage starts 2022-03-07. For coverage questions, bound a window or use lake.options_daily (completed session-boundary NBBO).

Inspect source dates and nullable fields before interpreting a result. A completed query is not proof that the source is current, complete for every security, or public at an event’s occurrence time.

Run a limited query

Use a registered API key with lake scope. Select needed columns, bind user-supplied values and restrict dates when the table has a time dimension. Query results are durable parts with a schema and manifest rather than an unbounded in-memory array.
