What is Difference Between Isolated Margin and Gross Margin on Binance
Binance Margin Trading supports cross margin and isolated margin now. You may select cross or isolated in the new trading page, as the following picture:
Margin in isolated margin mode is independent in each trading pair:
- Each trading pair has an independent isolated margin account. Only specific cryptocurrencies can be transferred in, held and borrowed in a specific isolated margin account. For instance, in BTCUSDT isolated margin account, only BTC and USDT are accessible; you may open several isolated margin accounts.
- Position is independent in each trading pair. If adding margin is required, even if you have enough assets in other isolated margin accounts or in the cross margin account, the margin will not be added automatically, and you may have to replenish manually.
- Margin level is calculated solely in each isolated margin account based on the asset and debt in the isolated.
- Risk is isolated in each isolated margin account. Once liquidation happens, it will not affect other isolateds.
For detailed rules about isolated margin trading, you may refer to Isolated Margin Trading Rules.
Margin in cross margin mode is shared among the user margin account:
- Each user can only open one cross margin account, and all trading pairs are available in this account;
- Assets in cross margin account are shared by all positions;
- Margin level is calculated according to total asset value and debt in the cross margin account.
- The system will check the margin level of the cross margin account and then send notification to user about supplying additional margin or closing positions. Once liquidation happens, all positions will be liquidated.
