Abstract: A method, system and computer program product for automatic securities trading. A graphical user interface comprising one or more spreadsheets is provided. Each of the spreadsheets comprises: a first section for receiving and displaying securities data; and a second section for receiving and displaying trading orders. Each of the trading orders comprises an execution trigger parameter, a volume parameter, a price parameter and a status parameter, which parameters are defined in spreadsheet cells. The securities data in the first section is repeatedly updated and the execution trigger parameters of the trading orders are repeatedly evaluated. Trading orders are executed responsive to a determination that the condition specified by the execution trigger parameter associated therewith is met.
