OneChicago trades are cleared at the AA+ rated Options Clearing Corporation (OCC), which functions as a central counterparty (CCP) to each trade participant. Firms that are approved to clear Single Stock Futures at OCC are qualified to trade for themselves and for customers at OneChicago.
To benefit from margin offsets against stock option positions, clearing must be conducted at the OCC.
