Abstract: Aggregating fixed income securities data from multiple market venues. Sets of data describing one or more fixed income securities are received from each of multiple market venues by a computer processor. Data contained within each of the sets of data is filtered to identify key/value data common to each set of data, the key/value data comprising, for each of the fixed income securities, securities industry identifier codes; a bid price; an ask price; a bid size; an ask size; a bid yield; an ask yield; a last trade price and quantity for executed trades; an execution time stamp; and a reference price. The filtered data is stored in a data repository.

Abstract: A system for tracking the status of a securities trade. A computer system serves as a node and communicates with at least one buy side computer associated with a party desiring to purchase securities and at least one sell side computer associated with a party desiring to sell securities. A communications channel couples the node with the buy side computer and the sell side computer. The node includes a message broker server and a database. The message broker server monitors messages transmitted by the buy side computer and the sell side computer, determines a present state of a trade based on the content of the messages, and stores the present state in the database.

Abstract: A securitas trading system including a node for facilitating transactions, at least one buy side computer associated with a party desiring to purchase, at least one sell side computer associated with a party desiring to sell and a communication channel coupling the node with the buy side computer and the sell side computer. The latency of the communications channel is determined in real time and parameters of a trade can be adjusted based on the latency and predetermined logic elements.
