I keep the books and the controls for two small companies, wrote the point-of-sale and inventory system one of them trades on, and built Lydon Quantitative, a nightly-retrained research and trading platform for CME futures. The thread through all of it is the same: understand how the thing actually works, write the rules down, and let the system enforce them.
