## Portfolio Margin Engine

A portfolio margin engine is the technical architecture that calculates the aggregate risk of a trader's entire portfolio rather than evaluating positions individually. It uses quantitative models to simulate market scenarios, determining the potential impact on the total account value.

This allows the engine to offer more flexible leverage based on the net risk profile of the assets held. By considering correlations between different crypto-assets, the engine can identify hedged positions that require less collateral.

This technology is essential for the scalability of large-scale derivative exchanges. It requires high-performance computing to provide real-time updates as market prices fluctuate.

The precision of these models directly affects the capital efficiency of all participants on the platform.
