## Protocol Margin Engines

Protocol margin engines are the automated software systems that manage leverage, collateral, and liquidations within a decentralized exchange or lending platform. These engines are responsible for calculating the health of every position in real-time.

They must ensure that the protocol remains solvent even during periods of extreme price movement. By utilizing oracles, they pull accurate price data to update margin requirements.

If a position falls below the required margin, the engine initiates the liquidation process to close the position. The efficiency and reliability of these engines are critical to the security of the entire protocol.

They represent the intersection of finance and robust software engineering.
