Abstract

A financial instruments trading system provides a front end user interface comprising dynamically generated tradescreens that enable the trader to calculate the effects of a hypothetical trade or transfer of a financial instrument on the corresponding portfolio and on aggregate holdings of the financial instrument in that portfolio before the trade or transaction is actually executed. The tradescreens display financial information characterizing the current status of the portfolio and the current status of all holdings of the financial instrument in the portfolio. The tradescreens further include fields for entry of information characterizing the hypothetical trade or transfer, and routines for calculating the revised values of the displayed financial information for the portfolio and the holdings of the financial instrument that reflect changes that will occur in the event that the hypothetical trade or transfer is executed. Each tradescreen further enables the trader to submit the trade or transfer for execution from the tradescreen. The tradescreens are dynamically generated by a server based on portfolio data maintained in a portfolio database, and are customized to the selected financial instrument and the type of action to be taken. The submission of a trade or transfer causes data entered into the tradescreen to be communicated to the server, where the tradescreen calculations are replicated and the portfolio database and a general ledger are updated to reflect the trade or transfer. The server also dynamically generates reports describing various aspects of the portfolio's holdings based on the data stored in the portfolio database.
