Cross Margin vs Maintenance Margin

A margin mode in which the entire account balance is available to prevent liquidation of any open position; useful for hedging strategies with offsetting positions, but risks total account loss if a large position moves severely against the entire book.

The minimum margin balance required to keep a leveraged derivatives position open; when the margin balance falls to this level, the exchange triggers automatic liquidation; typically 0.5% of notional value for standard-sized positions on major exchanges.
