These consist of four identifiers which describe transactions by the type of customer for which a trade is effected.. The four codes are: (1) trading for the member's own account; (2) trading for a proprietary account of the clearing member's firm; (3) trading for another member who is currently present on the trading floor or for an account controlled by such other member; and (4) trading for any other type of customer. Transaction data classified by the above codes are included in the trade register report produced by a clearing organization.
