In Binance Futures, margin mode controls how your collateral is shared across positions.

Let’s breakdown the difference between Isolated and Cross margin;

⭐️Cross margin: Margin is shared across all positions in the same futures wallet (e.g., USDⓈ-M wallet).

​If one position is losing, it can use available balance (and sometimes profits from other positions) to avoid liquidation.

​

Pros: Lower chance of liquidation from small drawdowns.

​Cons: A big loss in one position can drag down your whole wallet and risk liquidating other positions.

⭐️Isolated margin: Margin is “isolated” per position (you allocate collateral to that specific position).

​Liquidation risk is mostly limited to the margin assigned to that position.

​Pros: Cleaner risk control; one bad trade won’t wipe the whole wallet.

​Cons: Higher chance of liquidation if that position moves against you and you didn’t allocate enough margin.

What to take note is;

​Isolated for most directional/speculative trades (contain risk).

​Cross when you intentionally want to share margin and actively monitor risk.
