Lotus Development Corp has not had much fun with its various initiatives to come up with products aimed specifically at the securities-trading businesses, and after abandoning its ideas for a pager-type system to deliver share price quotations to investors on the move, it has now thrown in the towel on Lotus Realtime, the graphical real-time variant of the Unix version of the 1-2-3 spreadsheet aimed specifically at securities traders, portfolio managers and analysts wanting to enter and analyse real-time data. It is selling the product and companion technologies to Market Arts Software Inc, New York City on undisclosed terms, saying that it wants to focus on workgroup and desktop computing where its hottest property is the Notes groupware. Market Arts specialises in developing software products for financial institutions involved in trading, lending and investing.
