Understanding Isolated Margin Trading on OKX: Single-Cross-Portfolio Margin Modes

Introduction to Isolated Margin Trading

Isolated margin trading allows users to allocate a fixed amount of collateral per position, limiting risk exposure. OKX supports three margin modes:

1. Single-Currency Margin Mode

• Rule: Available balance of the traded currency must cover the order amount.
• Example: Trading BTC/USDT requires sufficient BTC balance for buy orders.

2. Cross-Currency Margin Mode

• Rule: Overall effective margin must exceed occupied margin (including pending orders), with traded currency balance covering the required collateral.

3. Portfolio Margin Mode

• Rule: Similar to cross-currency mode but optimized for diversified portfolios.

Isolated Leverage Trading

Key Concepts

• Position Assets: Total assets in the position (including collateral).

  • Long: Denominated in the base currency (e.g., BTC).
  • Short: Denominated in the quote currency (e.g., USDT).
• Liabilities: Initial debt + accrued interest.
• Maintenance Margin: Minimum collateral to avoid liquidation.

Example Calculation

Long BTC/USDT at 10x Leverage:

• Open 1 BTC position at $50,000:

  • Collateral: 0.1 BTC
  • Debt: $50,000 USDT
• Liquidation Price: Calculated based on maintenance margin and fees.

FAQ

Q1: What happens if my isolated margin position hits liquidation?

A: The position is closed automatically when collateral falls below maintenance margin.

Q2: Can I adjust leverage after opening a position?

A: Yes, but it affects your liquidation price and collateral requirements.

Q3: How is interest calculated on borrowed funds?

A: Interest accrues hourly based on the borrowed amount and current rates.

Q4: What’s the difference between cross and isolated margin?

A: Isolated margin limits risk per position, while cross-margin uses total account balance.

Q5: Are portfolio margin fees higher?

A: Fees vary by tier but may be lower due to risk-based offsets.
