Margin Call Trigger

A margin call trigger is the specific event or price level that forces a trader to add more collateral to their account to maintain an open position. When the value of a trader's collateral falls below a maintenance margin, the protocol issues a notification or initiates an automatic liquidation process.

This mechanism is designed to protect the protocol from the risk of the trader's position becoming underwater. In crypto markets, these triggers are often executed via smart contracts, making them immutable and instantaneous.

If the user fails to respond to the trigger by adding funds, the protocol liquidates the position to recover the debt. It is a fundamental tool for managing leverage and counterparty risk.

The trigger level is determined by the protocol's risk parameters and the asset's volatility. It serves as a final warning system before a forced liquidation occurs.
