The Options Symbology Initiative (OSI) is an industry plan to change the symbology used in representing options listed contracts. The OSI is being coordinated by Options Clearing Corporation (OCC). As a result of this initiative, DTN will be changing its Options symbology for all DTN platforms and begin disseminating the new equity and index
symbol format in accordance with the OCC and Options Symbology Initiative.
