Abstract: A machine-implemented method includes: obtaining transaction data relating to one or more financial assets, the transaction data including the identity of the one or more financial assets, corresponding valuation data for the one or more financial assets, and corresponding volume data for the one or more financial assets; receiving, at the data processing apparatus, a request to display information relating to a first financial asset from the one or more financial assets; generating, in response to receiving the request, output data for display at a user terminal, in which the output data includes a user interface that displays at least a portion of the transaction data relating to the first financial asset and market projection information relating to the first financial asset, in which the market projection information is substantially contemporaneous with the portion of transaction data; and transmitting the output data to the user terminal.
