Cross Margin and Isolated Margin Modes

Perpetual contracts offer two margin modes: Cross Margin and Isolated Margin. Each has distinct characteristics and is suited for different trading strategies and risk management approaches. Understanding the differences between these modes is essential for effective risk management in contract trading.

Cross Margin Mode

Cross Margin, also known as "cross-term margin," uses all available balance in your account to prevent positions from being liquidated. This means that profits from one position can help maintain another position that might be at risk of liquidation.

Key Characteristics of Cross Margin

1. Shared Margin Pool: All positions share the same margin pool, which includes your entire available account balance.
2. Dynamic Resource Allocation: The system automatically allocates margin resources to positions based on need.
3. Lower Liquidation Risk: With more funds available for margin, the risk of liquidation is generally lower compared to isolated margin.
4. Default Setting: By default, all positions are initially set to Cross Margin mode.

Advantages of Cross Margin

• Efficient Capital Utilization: Makes full use of all available funds in the account.
• Automatic Margin Adjustment: The system automatically allocates margin to positions that need it most.
• Protection from Liquidation: Available balance from profitable positions can help maintain positions that are at risk.
• Simplified Management: No need to manually adjust margin for individual positions.

Disadvantages of Cross Margin

• Higher Total Risk: If multiple positions move against you, your entire account balance could be at risk.
• Less Control Over Risk Allocation: Limited ability to control how much of your balance is at risk for a specific position.
• Potential Domino Effect: Losses in one position can affect the margin available for other positions.

Isolated Margin Mode

Isolated Margin allows you to allocate a specific amount of margin to each individual position. Your maximum loss is limited to the initial margin allocated to that position.

Key Characteristics of Isolated Margin

1. Segregated Margin: Each position has its own dedicated margin that is not shared with other positions.
2. Fixed Risk Exposure: The maximum amount at risk is the margin allocated to each position.
3. Manual Control: You must manually add margin if a position needs more to avoid liquidation.
4. Leverage Flexibility: Each position can have its own leverage setting.

Advantages of Isolated Margin

• Limited Risk Exposure: Losses are strictly limited to the margin allocated to each position.
• Better Risk Management: Allows precise control over how much is at risk for each position.
• Independent Position Management: Each position's risk is contained and does not affect other positions.
• Customized Leverage: Different leverage ratios can be set for different positions.

Disadvantages of Isolated Margin

• Higher Liquidation Risk: With less margin available per position, the risk of liquidation is higher.
• Manual Margin Management: Requires active monitoring and manual addition of margin when needed.
• Less Efficient Capital Usage: May lead to inefficient use of capital as margin is segregated.

Choosing Between Cross and Isolated Margin

When to Use Cross Margin

• When you want to maximize capital efficiency
• For long-term positions that you want to protect from short-term volatility
• When managing multiple correlated positions that you expect to balance each other
• For traders who prefer a simplified margin management approach

When to Use Isolated Margin

• When you want strict control over risk exposure
• For experimental or high-risk trading strategies
• When you have multiple unrelated positions with different risk profiles
• For traders who prefer detailed position-by-position risk management

Switching Between Margin Modes

1. From Cross to Isolated:

   • Navigate to the position you want to modify
   • Select "Isolated Margin"
   • Specify the amount of margin to allocate
   • Confirm the change

2. From Isolated to Cross:

   • Navigate to the position you want to modify
   • Select "Cross Margin"
   • Confirm the change

Note: When switching from Isolated to Cross margin, all margin from the isolated position will be returned to your available balance.

Important Considerations

1. Liquidation Process: In both modes, positions are liquidated when the margin ratio falls below the maintenance margin requirement. However, the calculation of margin ratio differs between modes.

2. Margin Calculation:

   • Cross Margin: Margin Ratio = (Total Balance + Unrealized PnL) / (Position Value)
   • Isolated Margin: Margin Ratio = (Allocated Margin + Unrealized PnL) / (Position Value)

3. Impact on Leverage: Changing margin modes can affect the effective leverage of your position. Always check the adjusted leverage after switching modes.

4. Market Volatility: During periods of high volatility, consider using isolated margin for higher-risk positions to prevent them from draining your entire account balance.
