Liquidation Trigger

A liquidation trigger is an automated mechanism in derivative protocols that monitors the health of a leveraged position and initiates a forced closure if it falls below a specific threshold. This threshold is typically defined by the maintenance margin requirement, which is the minimum collateral value needed to support the open position.

When the value of the collateral drops due to adverse price movements, the liquidation trigger automatically executes a market order or auction to sell the collateral and cover the debt. This ensures the protocol remains solvent and protects lenders from losses in volatile markets.

The trigger relies on accurate price feeds, often provided by oracles, to determine when a position has become under-collateralized. Because this process happens on-chain, it is deterministic and designed to operate without human intervention.

The speed and efficiency of the liquidation trigger are vital for maintaining market microstructure stability during rapid price swings.
