Basic Concepts of Cross and Isolated Margin
In Binance futures and margin trading, Cross Margin and Isolated Margin are two different margin modes. Your choice directly affects how you manage risk and under what conditions liquidation occurs. Understanding the difference between these two modes is essential before engaging in futures trading.

Cross Margin Mode
In Cross Margin mode, all available balance in your futures account serves as margin for all positions. Simply put, your entire balance provides "backup" for all open positions.
Advantages:
- Harder to get liquidated, since all balance can absorb losses
- Multiple positions share margin — profitable positions can subsidize losing ones
- Higher margin utilization efficiency — you can open more positions with the same capital
- Suitable for simultaneously holding multiple correlated positions
Disadvantages:
- If liquidated, you may lose all funds in your account
- Risk isn't isolated — one bad position can drag down the entire account
- Difficult to precisely control each position's risk exposure
Example: Suppose you have 1,000 USDT in your futures account and open a BTC long position. In Cross Margin mode, even if BTC drops and this position shows an unrealized loss of 500 USDT, the system will still use your remaining 500 USDT to maintain the position without immediate liquidation. However, if BTC continues falling until all 1,000 USDT is lost, your entire account goes to zero.
Isolated Margin Mode
In Isolated Margin mode, each position has independently allocated margin, and positions don't affect each other. You set how much margin to use for each position individually.
Advantages:
- Risk isolation — liquidation of one position doesn't affect other positions or account balance
- Maximum loss is limited to the margin allocated to that specific position
- Easier to manage each position's risk — you know exactly how much each trade can lose at most
- Suitable for testing uncertain trading strategies
Disadvantages:
- Liquidation triggers more easily since available margin is limited
- Requires manual management of margin allocation for each position
- If a position nears liquidation, you need to manually add margin, or it will be force-closed
Example: With the same 1,000 USDT account, you allocate 200 USDT margin to a BTC long position. If BTC drops enough to approach a 200 USDT loss, this position gets force-liquidated. But the remaining 800 USDT in your account stays intact, and other positions are unaffected.
How to Choose?
Beginners: Isolated Margin recommended: While it's easier to get liquidated, maximum loss is controllable. Each position's risk is independent, so one mistake won't cost you all your capital. You can clearly know the worst-case outcome of each trade, which is crucial for building good risk awareness.
Experienced traders can use Cross Margin: It allows more efficient capital utilization and managing multiple positions simultaneously. With shared margin, the same capital can support more positions, improving capital efficiency.
Practical Tips
Isolated Margin tips:
- The margin allocated to each position represents the maximum loss you're willing to accept on that trade
- We recommend each position's margin should not exceed 10%-20% of total account funds
- If a position nears liquidation but you still believe in the direction, you can manually add margin
Cross Margin tips:
- Don't max out your positions — keep at least 30% of your account as idle margin
- Monitor the maintenance margin ratio — when it falls below a certain threshold, reduce positions or add funds promptly
- Hedging positions (simultaneously going long and short on different assets) work better in Cross Margin mode
In practice, you can flexibly choose based on different strategies. Use Cross Margin for high-conviction trades and Isolated Margin for exploratory trades to control risk. In the Binance APP, you can switch between the two modes at any time before placing an order by tapping the "Cross/Isolated" button at the top of the trading page. Note: Switching modes only affects new positions — existing positions remain unchanged.
