Get market-maker spread
Returns market-maker spread in bps (basis points) per organization, exchange, pair and bucket. Combines reported and trusted values: in each bucket a trusted value replaces the reported one, and is_trusted marks rows that contain trusted data. Market makers see their own organization’s values; project owners see every market maker’s values for the assets they own. Per-wallet rows (source is wallet) are returned to staff, and to market makers for their own wallets. With interval=a each row covers the whole range and has no timestamp.
