Cross-margin trading is a risk-management strategy that allows traders to use all the funds in their accounts to prevent liquidation. It's a method that uses the full balance to keep open positions rather than just the initial margin used to open the position.
In cross-margin mode, all available balance in the trader's account is used as collateral for their open positions. If a position starts to incur a loss, the cross margin strategy will use all available funds in the account to add margin and prevent the position from being liquidated.
While this can be a useful tool for preventing liquidation, it also carries significant risks. If the market moves against the trader's position, it could result in the loss of the entire balance in their account. Therefore, cross-margin trading should be used with caution and is generally recommended for more experienced traders who understand the risks involved.
