What Is the Difference between Front-Running and Latency Arbitrage in Traditional Options Trading?

Front-running is illegal and involves using non-public information about an impending large order to trade ahead of it. Latency arbitrage is a legal, high-frequency trading strategy where a firm exploits tiny price differences between exchanges by being faster.

While both rely on speed, front-running is based on informational advantage (insider knowledge), whereas latency arbitrage is based on technological advantage (speed and connectivity).
