What is cross margin mode?

Hello Sir/Madam,

Cross-margin mode is available in Huobi Futures: the same digital currency asset of your account will be used as margin of all the open positions of that digital currency.

For example, if you open one position of BTC contracts, then all the BTC in your account will be the margin of that position, and if you open several positions of BTC contracts, then all the BTC in your account will be the margin shared by these open positions. The profits and losses of positions of one digital currency can be mutually offset.
