When trading futures on Binance, you need to choose between "Isolated" and "Cross" margin modes. This choice directly affects your risk exposure and position management. Choosing incorrectly could lead to unexpected losses. Here's a detailed explanation of both modes to help you make the right choice. Sign up on Binance and open a futures account to set your margin mode.
What Is Cross Margin Mode?
Concept
Cross Margin means your entire available futures account balance can serve as margin to maintain all your positions. In other words, all your funds collectively support all your positions.
How It Works
Say your futures account has 1,000 USDT:
- You open a BTC long position with 100 USDT margin
- If the market moves against you and BTC drops
- The system automatically draws from the remaining 900 USDT to supplement your margin
- Liquidation only occurs when the entire 1,000 USDT is consumed
Characteristics
- Liquidation price is farther from entry (because more margin is available)
- If liquidation occurs, the entire account balance is lost
- Different positions can support each other
- Profitable positions can offset margin shortfalls from losing positions
What Is Isolated Margin Mode?
Concept
Isolated Margin means you allocate a specific amount of margin to each position independently. Each position's margin is separate and doesn't affect the others.
How It Works
With the same 1,000 USDT account:
- You open a BTC long position with 100 USDT margin (isolated)
- If BTC drops
- Only the 100 USDT allocated to this position serves as margin
- Liquidation occurs when that 100 USDT is consumed
- The remaining 900 USDT in your account is unaffected
Characteristics
- Maximum loss per position is clearly defined (the allocated margin)
- One position's liquidation doesn't affect others
- Liquidation price is closer to entry (because margin is smaller)
- Different margins can be allocated to different positions

Side-by-Side Comparison
Risk Control
| Dimension | Cross Margin | Isolated Margin |
|---|---|---|
| Maximum loss | Could lose entire account | Only lose allocated margin |
| Liquidation distance | Farther from entry | Closer to entry |
| Risk controllability | Lower | Higher |
| Multiple positions | Positions support each other | Each managed independently |
Example Comparison
Account balance: 1,000 USDT, BTC long, 10x leverage, 1,000 USDT position value
Cross Margin:
- Margin = 1,000 USDT (entire account balance)
- Can withstand approximately 100% drop (theoretical)
- Liquidation costs 1,000 USDT
Isolated Margin (100 USDT allocated):
- Margin = 100 USDT
- Can withstand approximately 10% drop
- Liquidation only costs 100 USDT, remaining 900 USDT is safe
What Should Beginners Choose?
Isolated Margin Is Strongly Recommended
For beginners, isolated margin is safer for these reasons:
- Controllable losses: Maximum loss per position is clear — you won't lose all funds at once
- Low learning curve: No need to consider inter-position margin dynamics
- Lower psychological pressure: Knowing the worst-case outcome keeps you calmer
- Easy management: Each position is independent, making it simple to evaluate individual trades
When to Use Cross Margin
Cross margin is better suited for experienced traders:
- When you have high conviction in the market direction
- When you need multiple same-direction positions to support each other
- When your positions are large and you don't want frequent liquidations
- When you can manage your entire account's risk exposure
How to Switch Margin Modes
Steps
- Go to the futures trading page
- Find the "Cross" or "Isolated" label next to the leverage selector
- Tap to switch modes
- Note: Switching may be restricted while you have open positions
Important Notes
- Understand the new mode's risk characteristics before switching
- You may not be able to switch while holding open positions
- Each trading pair can have its own independent mode setting
Margin Management in Practice
Adding Margin in Isolated Mode
If the market is moving against you but you still believe in the direction, you can manually add margin in isolated mode:
- Find the position in your position list
- Tap "Add Margin"
- Enter the amount to add
- The liquidation price moves farther away after confirmation
Fund Management in Cross Mode
In cross margin mode, avoid putting all your funds in the futures account. Keep some in your spot account to prevent losing everything at once.

FAQ
Can I use both modes in the same account?
Yes. Binance lets you set different margin modes for different trading pairs. For example, BTC futures on cross margin and ETH futures on isolated margin.
How do I add margin in isolated mode?
Tap the "+" or "Add Margin" button next to the corresponding position in your position list.
Does a losing position in cross mode affect other positions?
Yes. In cross margin mode, all positions share margin. One position's losses consume account balance, potentially affecting other positions' liquidation prices.
Are fees different between the two modes?
Fees are exactly the same. The only difference is how margin is managed. Download the Binance App to flexibly use different margin modes in futures trading.
Safety Tips
- Beginners must use isolated margin mode and strictly control the maximum loss per trade
- Don't open too many positions in cross margin mode to avoid cascading liquidations
- Keep each trade's margin to 5-10% of total funds
- Always set stop-losses — don't rely on the margin mode alone to protect your funds
- Regularly evaluate your risk exposure to avoid overexposure
