This video examines the 2012 Knight Capital Group incident, widely regarded as the most expensive software bug in history. It details how a deployment error and legacy code reactivation led to massive financial losses within minutes.

■ The Root Cause of the Incident
- The implementation of the NYSE Retail Liquidity Program required updating Knight's SMARS system.

- Manual deployment processes resulted in only seven out of eight servers receiving the update.
- One server continued running the outdated logic while others processed new orders correctly.
- A panic-induced rollback synchronized all servers to the faulty state, exacerbating the damage.

■ Financial Impact and Industry Lessons
- The company executed 4 million trades in 45 minutes, losing $440 million.
