How should the share quantity for an order event that involves a fractional number of shares be reported? For example, an order for 100-1/2 shares is received and worked by routing away 100 shares and executing the remaining 1/2 share as principal.
CAT allows for the reporting of fractional shares in decimal format. In this example, the share quantity for the New Order Event should be 100.5, the Order Route Event should be 100, and the share quantity on the Trade Event for the fractional principal execution should be 0.5.
