While working at the Royal Bank of Canada (RBC), the global electronic trading team led by Brad Katsuyama, Ronan Ryan, John Schwall, and Rob Park discovered that stock exchanges were enabling predatory trading strategies that were harming long-term investors such as mutual funds and pension funds that represent the savings of millions of Americans.
