The break tracking system allows comparison of the at least two sets of information to determined whether a break exists. If a break is determined to exist, the break tracking system allows identification of one or more traders evidenced in the networked computer system as being associated with the break, can allow providing electronic notification of the break to trader computers associated with the traders, and can provide a break tracking application facilitating electronic communication between users of trader computers for facilitating resolution of the break.

Abstract: This invention provides methods and systems for facilitating trading of securities over a communications network. The methods and systems allow users to submit orders for trading securities with a consolidated order entry interface screen for single and multiple orders. The consolidated order interface screen provides the user with a single order entry point for submitting orders to trade securities of different types. The consolidated order interface screen, in one embodiment, provides the user with a centralized order entry point for a plurality of security trading platforms. Each of the plurality of security trading platforms may processes orders for given types of a securities, for particular types of security orders, or for particular types of users. Orders to trade securities are tested to determine if they are valid or otherwise capable of being executed.
