G. Griffin Lewis

“In 2008, Citadel bought a stake in the online broker E*Trade, which was foundering in the credit crisis. The deal stipulated that E*Trade route some percentage of its customers’ orders to Citadel. At the same time, E*Trade created its own high-frequency trading division, eventually called G1 Execution Services, to exploit the value of those orders for itself. Citadel’s founder and CEO, Kenneth Griffin, pitched a fit, and called out E*Trade for failing to execute its customers’ orders properly.””
