## Liquidation Engine Trigger

A Liquidation Engine Trigger is a programmed condition that initiates the process of closing undercollateralized positions within a financial derivative protocol. When the value of collateral backing a loan or derivative position falls below a required maintenance threshold, the engine automatically triggers a liquidation.

This mechanism protects the protocol and its lenders from insolvency by ensuring that bad debt is cleared promptly. The trigger relies on accurate, real-time price feeds to determine if the position is still healthy or if it needs to be liquidated.

It is a critical component of risk management in leveraged trading environments. By automating this process, the protocol removes the need for manual intervention and ensures fair, objective enforcement of risk rules.

The trigger must be highly reliable to prevent catastrophic failures during market crashes.
