Cross Margin Systems
Cross Margin Systems allow traders to share collateral across multiple open positions, using the equity from profitable trades to support those that are currently losing. This approach provides greater capital efficiency compared to isolated margin, where each position must be funded independently.
By pooling collateral, the system reduces the likelihood of individual positions being liquidated due to temporary price volatility. However, it also increases the risk of a single bad trade affecting the entire account's health.
If the total collateral falls below the required threshold for all combined positions, the entire portfolio is at risk of liquidation. These systems are favored by active traders who manage complex portfolios of derivatives.
