A single proprietary trading firm can have enough computers to fill your house ten times and then some. Each of these computers can easily be $50,000 or more. These firms have zero problem hiring the best programmers in the world for $500 per hour or more to program some of the most complicated programs that ever existed. I’m telling you that people trading at proprietary firms are at least as smart as NASA engineers and sometimes smarter. Except for a tiny number of individuals devoted to making this world a truly better place, in this world, money is a much more powerful motivator than the pursuit of scientific progress. Don’t believe me? A NASA engineer earns something like $100,000 per year. A good trader can EASILY earn $100,000 per DAY. EASILY.
