Cross-Margin Accounts
Cross-Margin Accounts allow traders to use the entire balance of their account as collateral for all open positions. If one position incurs a loss, the gains from other positions can be used to cover it, preventing immediate liquidation.
This system provides more flexibility than isolated margin, where each position is treated independently. While cross-margining is more capital-efficient, it also carries higher risk, as a significant loss in one position can deplete the entire account balance and lead to the liquidation of all open positions.
It is a popular feature in derivatives exchanges, catering to experienced traders who want to manage their overall risk exposure dynamically. The complexity of cross-margin systems requires robust risk management and monitoring tools to ensure that the total account value remains sufficient to cover the aggregate risk of all open positions.
