Cross Margin
A margin mode where the entire account balance backs every open position — improving capital efficiency but exposing the whole account to any single losing trade.
In cross margin, every position on the account shares one collateral pool. Profitable positions effectively support losing ones, and the liquidation engine only forces a liquidation when the entire account's equity falls below maintenance margin.
The mode is materially more capital-efficient than isolated margin and suits delta-neutral or hedged strategies that have offsetting exposures. The risk is that one big losing trade can cascade through and liquidate the entire account at once.
