Cross margin & isolation margin.

1. What is cross margin?
Cross-margin is a transaction method that maintains a position by using the entire account balance.

If the net asset value cannot meet the demand for the maintenance deposit ratio, the position will be forcibly liquidated and the balance held by the account will be "all" lost.

2. What is isolation margin(ISO)?
The isolation margin is a function that separates the margin used when opening a position from the account balance, and uses some of the funds in the margin in the contract.

If you apply this function, you can't use additional margin, so you can reduce your losses to the maximum when you're forced to liquidate. The maximum amount that can be lost when using the isolation margin is the starting margin of the position, which allows traders to control risks.

The isolation margin is suitable for high leverage and scalping, but if the coin market price changes unexpectedly, it can be forced to liquidate immediately. Also, the isolation margin depends on the amount of leverage.
