API Failover Mechanisms

API Failover Mechanisms are technical protocols designed to automatically switch trading operations to a backup system if the primary API connection to an exchange fails. This ensures that a trader's automated systems can continue to manage risk and execute orders without interruption.

If an exchange's API becomes unresponsive or starts returning errors, the failover system detects this and redirects traffic to an alternative connection or a different exchange entirely. This is critical for maintaining market participation during periods of high volatility when downtime is most costly.

It is a fundamental aspect of robust algorithmic trading architecture.
