In the wake of what could be the worst economic crisis since the Great Depression, Wall Street could use a fresh start. Which is why the New York Stock Exchange is undergoing a $5-million interior redesign. The aim is to make the trading floor more attractive to brokers, who no longer jam the NYSE like they once did. While five years ago, actual people on the floor were involved in 85 per cent of trading at the NYSE, today only 15 per cent of trading involves humans; the number of traders manning posts and booths has plummeted from 3,300 to 1,000. The project, which is slated to wrap up in 18 months, is intended to give the NYSE a more up-to-date look, transforming the entire back side of the main trading space and creating a new wing that will resemble a modern office trading floor.
