Dealer / Intermediary Asset Manager Leveraged Money Other Reportable Non-Reportable

The classic Commercial / Large Speculator split is not offered for financial futures. The CFTC's financial taxonomy (Dealer, Asset Manager, Leveraged Money) is a different cut rather than a subdivision of the legacy one, and no combination of its categories reproduces the legacy figures, so presenting one would be a guess.
