Cross Margin Calculation

USDT Contract uses a multi-currency cross-margin calculation method to allow traders to adopt better trading strategies, especially for hedgers, who can hedge against multiple currencies in one account.

For example, if you hold the BTC/USDT position with an unrealized profit of 100USDT while holding the ETH/USDT position with an unrealized loss of 50USDT, then the total unrealized PNL is +50USDT.
