## Cross Margin Vs Isolated Margin

Cross margin and isolated margin represent two different approaches to managing collateral in derivatives trading. In isolated margin, the collateral is restricted to a single position, meaning the potential loss is limited to that specific amount.

If that position is liquidated, it does not affect the rest of the trader's account. In contrast, cross margin uses the entire balance of the account as collateral for all open positions.

While this provides more flexibility and can prevent liquidation during temporary price dips, it also puts the entire account balance at risk if a single position moves significantly against the trader. Choosing between these modes depends on the trader's risk appetite and portfolio strategy.

Cross margin is often preferred by institutional traders for its capital efficiency, while retail traders often favor isolated margin for its clearly defined risk boundaries. Understanding these modes is essential for preventing unintended losses across a portfolio.
