Dark Pool

Paginated off-exchange (TRF) prints

Server-side filtered dark-pool prints from the off-exchange tape (FINRA TRF, publisher FINN/FINC). Defaults to today (ET) with a $1,000,000 minimum notional (the blocks-by-default rule); pass min_notional=0 for the full firehose. The trade-date span is capped at 31 days per request — page with limit/offset or narrow the range for more. Prints carry no side, BBO, or greeks. Pagination state (limit, offset, count, hasMore) is returned in meta.
