What Is the Difference between Isolated and Cross Margin in Leverage Settings?
Isolated margin dedicates a specific, isolated amount of capital to a single position. If the margin for that position is lost, only that position is liquidated, and the rest of the account's funds are safe.
Cross margin uses the entire available balance in the account as collateral for all open positions. This reduces the risk of liquidation for a single position but exposes the entire account to the risk of a market-wide downturn.
