The present invention involves a security management and trading system and method which maintains persistent control over time sensitive data. The system interacts with data processing systems transacting the purchase and sale of at least one security having a set of characteristic data. The data processing system is operated by a plurality of trading participants and transmits information relating to the securities characteristic data. The trading system comprises a network (LAN), a workstation (14), and a server (12). The workstation is coupled to the network and includes a display (18) for presenting to a participant information about pending market conditions as they relate to the security characteristic data of at least one security. The server is in communication with the workstation over the network and provides event information to the workstation. At least one of the workstation and server includes an object oriented software program (OMI) comprising a plurality of objects. The workstation includes a securities evaluation software application (SE) which references an object having time sensitive security characteristic data. The workstation also includes persistent control software (PC) having instructions for enabling the workstation to update the object having the time sensitive security characteristic data when external event information is received and is relevant to the time sensitive securities data.
