Using Cross-Margin Unrealized PnL to Fund Additional Futures Positions

Summary

The document explains how supported unrealized profit from a Cross Margin futures position can contribute to available margin for opening another position while the original trade remains open. It distinguishes unrealized PnL, which changes with market prices, from realized profit after a position is closed or settled. It contrasts Cross Margin’s shared pool with Isolated Margin, where a position’s PnL does not support other positions through that pool.

The article gives simplified balance examples and describes a workflow: choose Cross Margin, open a position, check available margin and other account obligations, then assess whether another trade is supportable. It cautions that a reversal can reduce floating profit and available margin while multiple positions remain open, increasing liquidation risk. Actual usable margin also depends on factors such as leverage, fees, pending orders, maintenance requirements, and account liabilities. The explanation is platform-specific, and its formulas are simplified rather than a complete margin calculation.

Key ideas

• Supported unrealized profit in Cross Margin can increase funds available for another futures position.
• Unrealized PnL remains variable until the position is closed or settled.
• Isolated Margin keeps position margin separate, so its unrealized profit does not feed the shared Cross Margin pool.
• A market reversal can reduce available margin and increase liquidation risk across open positions.
• The amount available for a new trade depends on other margin requirements and account obligations.
