When trading futures on digital asset platforms, understanding how margin works is essential to managing risk and maximizing returns. One of the most critical decisions traders make is choosing between isolated margin and cross margin modes. This guide will clearly explain the differences, benefits, and practical applications of both systems—specifically within the context of OKX, a leading global cryptocurrency exchange.
Whether you're new to futures trading or looking to refine your strategy, this breakdown will help you make informed decisions based on your risk tolerance and trading goals.
What Is Account Equity?
Before diving into margin types, it's important to understand account equity, which represents the total value in your futures account.
Account Equity = Deposit Amount + Realized P&L + Unrealized P&L
- Deposit Amount: Funds you've transferred into your contract account.
- Realized P&L: Profits or losses from positions that have been closed.
- Unrealized P&L: Floating gains or losses from open positions.
While realized profits are factored into your equity and can be used as margin, they cannot be withdrawn until after settlement—especially in deliverable contracts. After a contract expires and settles, any realized gains can be transferred back to your main account.
Realized vs. Unrealized Profit and Loss
Realized Profit and Loss (P&L)
This refers to the gains or losses locked in when you close a position. Once a trade is settled, the profit or loss becomes "realized" and is added to your account equity.
For example:
- You open a long position on BTC/USDT with 1 BTC at $30,000.
- Later, you sell at $35,000.
- Your realized profit is $5,000.
This amount increases your equity and can be used to open new positions—but it remains in the futures account until settlement allows withdrawal.
Unrealized Profit and Loss (Floating P&L)
Also known as floating profit or loss, this reflects the current value of your open positions based on market prices.
If the market moves favorably after opening a position, you’ll see positive unrealized P&L. Conversely, adverse price movements result in negative unrealized P&L.
This value fluctuates in real time and directly impacts your available margin and liquidation risk.
Margin Systems: Isolated vs. Cross
OKX offers two distinct margin models for futures trading: Isolated Margin and Cross Margin. Each serves different trading strategies and risk profiles.
Cross Margin (全仓保证金)
In cross margin mode, all funds in your futures account act as collateral for all open positions. This means:
- All positions share the same pool of margin.
- Gains from one position can offset losses from another.
- The system automatically uses your total equity to prevent liquidation.
✅ Best for: Traders who want maximum capital efficiency and are comfortable with interconnected risk across positions.
🔹 Example:
You hold both a long BTC and short ETH position. If BTC drops but ETH rises sharply, the profit from ETH helps sustain the BTC position, reducing liquidation risk.
⚠️ Risk: A major market downturn could affect all positions simultaneously, increasing overall exposure.
Isolated Margin (逐仓保证金)
With isolated margin, each position has its own dedicated margin. You set a fixed amount of collateral for each trade.
Key features:
- Margin is isolated per contract.
- Only the allocated funds are at risk.
- Price movement affects only that specific position’s margin ratio.
- Easier to calculate risk per trade.
✅ Best for: Risk-conscious traders using defined strategies with strict stop-loss rules.
🔹 Example:
You allocate 0.1 BTC as isolated margin for a long position. Even if other positions fail, only this 0.1 BTC is exposed. If the price hits liquidation, nothing beyond that amount is lost.
⚠️ Limitation: Less flexibility during volatility since no additional funds are pulled in automatically.

Understanding Margin Ratio and Adjustment Coefficient
The margin ratio determines how close your position is to liquidation. It’s calculated as:
Margin Ratio = (Total Margin / Required Margin) – Adjustment Coefficient
Where:
- Total Margin: Includes initial margin + unrealized P&L
- Required Margin: Based on position size and leverage
- Adjustment Coefficient: Varies by contract type and leverage level
| Contract Type | 10x Leverage Coefficient | 20x Leverage Coefficient |
|---|---|---|
| (Note: Table removed per instructions) |
Instead of tables, here's a clear breakdown:
For BTC contracts, the adjustment coefficient is typically 10% at 10x leverage and 20% at 20x leverage.
For LTC contracts, it’s higher—20% at 10x and 40% at 20x—reflecting greater volatility or risk weighting.
A lower margin ratio means higher risk of liquidation. When the ratio drops to zero or below, the position may be automatically closed.
Traders should monitor this closely, especially under high leverage or volatile conditions.
Frequently Asked Questions (FAQ)
Q1: What happens to my realized profits after settlement?
After a futures contract settles (e.g., quarterly delivery), realized profits become available for transfer to your spot wallet or withdrawal. Until then, they remain part of your futures account equity but cannot be moved out.
Q2: Can I switch between isolated and cross margin during a trade?
No—you cannot switch modes once a position is open. You must close the current position and reopen it under the desired margin mode. Always plan your margin strategy before entering a trade.
Q3: Which margin mode is better for beginners?
Beginners often benefit more from isolated margin because it limits risk to a predefined amount. This prevents unexpected losses from spreading across multiple trades due to shared equity.
Q4: Does cross margin reduce liquidation risk?
Yes—because all account equity supports open positions, cross margin provides a larger buffer against liquidation. However, this also means total account funds are exposed if the market moves sharply against you.
Q5: How does unrealized P&L affect my margin?
In cross margin, unrealized P&L directly affects your total equity and thus your margin ratio. In isolated mode, only the P&L of that specific position impacts its margin status.
Q6: Can I use both margin types at the same time?
Yes—OKX allows you to use isolated margin for some contracts and cross margin for others. This flexibility lets advanced traders mix conservative and aggressive strategies simultaneously.
Choosing the Right Strategy
Your choice between isolated and cross margin should align with your trading style:
Use isolated margin when:
- You want strict risk control per trade.
- You’re testing a new strategy.
- You’re trading high-volatility altcoins.
Use cross margin when:
- You’re confident in portfolio diversification.
- You’re running multiple correlated positions.
- You want to maximize capital utilization.
