Comma-separated venue filter, e.g. deribit,bybit. Restricts the response to those venues' contribution, recomputed from the per-venue breakdown - it is a re-aggregation, not a post-hoc scaling. Unknown names are ignored; an all-invalid filter returns every venue rather than nothing. Venues: deribit, bybit, okx, binance, derive, thalex, delta_india, delta. A venue with no contracts on the surface contributes zero - use GET /v2/status to tell that apart from a venue that is switched off.

Dealer positioning model. flow (default) is BackQuant's measured dealer model, available for BTC/ETH; it falls back to std when it cannot be produced for a symbol. std is the textbook convention (call:+OI / put:-OI). The response reports which model actually ran in meta.extra.positioning.
