- It backs one trade with specific collateral.
- It separates one trade's risk from your main balance.
- Cross margin shares all account collateral.
- Rules and liquidation steps differ by exchange.
Margin trading lets you open a position larger than your deposit. On many exchanges you pick between isolated and cross margin before you open a trade. That choice decides which funds back the position and how far a loss can spread.
What Is an Isolated Margin Position?
You assign a set amount of collateral to that single trade. That collateral is the margin for the position. The rest of your account balance stays separate.
How Does It Work and What Limits?
The exchange treats the assigned collateral as the only funds backing the trade. If the margin falls below the maintenance level, the exchange can liquidate that position alone. Each exchange sets its own rules and liquidation process.
The trigger point and the way a position is closed can differ between platforms. Check the exchange's documentation for the exact process.
How Do Traders Use It?
Traders use it to keep one trade's risk separate from their main balance. If the trade fails, only the assigned collateral is lost. The rest of the account stays untouched.
- Separate a single trade from the main balance.
- Limit damage from one market move.
- Keep other positions safe from a liquidation.
How Is It Different From Cross Margin?
Cross margin is the alternative. It shares all account collateral across positions. A loss in one trade can draw on the whole balance.
