The next Wall Street tycoon will be a computer program

Novelist Matthew Klein concocted a flamboyant fictional character in his book, Con Ed, who claimed that his dotcom company had the technology to accurately predict the stock market. Wall Street observer Matthewsuch things were already happening in real life; and then dotcom entrepreneur Matthew Klein founded Collective2.com and made it into reality. In a behind-the-scenes look at how today's traders operate, we see that much of the decision-making really is made by computers -- and that Wall Street will never be the same again

We always see images in the movies of frantic traders shouting and waving pieces of paper, is it really still like that?

I don't think there have been pieces of paper or frantic traders since the Reagan administration. The popular image of human beings doing most of the trading and speculating on Wall Street disappeared in reality long ago. Today the biggest volume is traded by computers and software. Almost every investment bank has a proprietary trading arm that uses algorithmic trading methods to make decisions in an automated fashion. And while there are still human beings that make trading decisions -- let's call them "discretionary traders" -- these human beings ultimately rely on computer programs to make their trades happen. They rely on sophisticated computer programs to execute their trades in a very clever way, to send them down to the electronic markets, and to disguise their intentions so that their competitors don't know what they're up to. To summarize, computers do almost everything for traders nowadays.
