Cross Margin
Cross margin is a risk management strategy where the entire balance of a trading account is used as collateral for all open positions. If one position incurs losses, the protocol draws upon the total available equity in the account to maintain the margin requirements.
This approach provides more flexibility than isolated margin because it prevents premature liquidations caused by temporary volatility in a single asset. However, it significantly increases the risk to the entire portfolio, as a single losing trade can lead to the liquidation of all active positions.
Traders must carefully manage their total account exposure when utilizing cross margin, as the failure of one asset can drain the collateral meant for others. It is widely used by experienced traders to optimize capital efficiency across diverse derivative holdings.
