Cross-Margin versus Isolated Margin

Collateral

Margin methodologies delineate risk exposure within leveraged positions, fundamentally impacting capital efficiency and potential loss magnitude. Cross margin utilizes an aggregate account balance across all open contracts as collateral, allowing for higher leverage but exposing the entire portfolio to liquidation if any single trade performs adversely. This interconnectedness necessitates a comprehensive understanding of correlation between assets to accurately assess systemic risk, and is often favored by experienced traders comfortable with portfolio-level risk management.
