Steve Swanson was a typical 21-year-old computer nerd with a very atypical job. It was the summer of 1989, and he’d just earned a math degree from the College of Charleston. He tended toward T-shirts and flip-flops and liked Star Trek: The Next Generation. He also spent most of his time in the garage of his college statistics professor, Jim Hawkes, programming algorithms for what would become the world’s first high-frequency trading firm, Automated Trading Desk.
