Brokers ranked by gross trade value (default) or absolute net flow for a single date. Optionally filter by origin (foreign/domestic) and cohort (retail/mixed/institutional/unknown). Returns all matching brokers if n_brokers is omitted. Each row also reports the portion of the broker's turnover executed for foreign investors (foreign_gross, foreign_net); pass foreign=true to rank by those instead of the totals.

<Note>Origin and cohort classifications come from the broker registry and describe the broker itself (a foreign- or domestic-owned member), not its clients. Use the foreign_* fields for investor-origin flow. Retrieve the full list with these classifications from the Broker Registry endpoint.</Note>
