Cross Margin vs Margin Ratio

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 current margin balance divided by the maintenance margin requirement, expressed as a percentage; when the margin ratio reaches 100%, the exchange triggers liquidation; real-time monitoring of margin ratio is the core operational discipline for managing leveraged positions.
