CYIOS Corporation (CYIO)

[surfkast]

If the firm facilitating the customer long sale order has either no position or a short position in the security in its trading account, the trade with the other firm is reported as short and included in the short sale volume calculations in the Daily File. The volume associated with the firm’s purchase from its customer, however, is not reflected in the Daily File. Thus, the firm’s short sale is included in the short sale volume calculations without any indication that it is associated with an offsetting purchase to facilitate a customer long sale.
