What Is the Difference Between Isolated Margin and Cross Margin?

When trading derivatives on NodeXX, margin refers to the amount of funds allocated to support a leveraged position. While the term "margin" can have different meanings in finance, in cryptocurrency derivatives trading it simply refers to the collateral used to secure your trades.

The two primary margin modes available on NodeXX are Isolated Margin and Cross Margin.

Isolated Margin

Isolated Margin allows you to allocate a specific amount of margin to each individual position.

This means that the risk of a position is isolated and limited to the amount of margin assigned to that specific trade.

Example

Suppose you open a BTC perpetual futures position using 1,000 USDT in Isolated Margin mode.

In this case:

• The maximum loss for that position is limited to the allocated 1,000 USDT.
• Even if your account contains additional funds, they will not be used to support the position.
• If the position reaches its liquidation price, only the assigned margin will be lost.

As a result, the rest of your account balance remains unaffected and available for other trading opportunities.

Cross Margin

Cross Margin uses all available funds in your derivatives account as shared margin across your positions.

This means that your entire available balance can be used to prevent any open position from being liquidated.

Example

Suppose your derivatives account contains 10,000 USDT, and you open one or more positions using Cross Margin mode.

In this case:

• The entire 10,000 USDT balance can be used as collateral.
• If one position moves against you, the system may draw from your remaining account balance to help maintain the position.
• This can delay or prevent liquidation compared to Isolated Margin.

However, if losses continue to increase, a single unsuccessful position could eventually consume all available funds in the account.

When Should You Use Each Margin Mode?

Isolated Margin: Better Risk Control

Isolated Margin is generally preferred when you want strict control over the risk of an individual trade.

For example, if you allocate 1,000 USDT to a position:

• Your maximum loss is limited to that 1,000 USDT.
• Even if the market moves dramatically against your position, the remainder of your account balance remains protected.
• Your other assets are unaffected and remain available for future trades.

This makes Isolated Margin particularly suitable for:

• New traders
• Risk-conscious traders
• High-volatility market conditions
• Traders who prefer clearly defined maximum losses

Cross Margin: Greater Capital Efficiency

Cross Margin can make more efficient use of your available capital because all account funds are pooled together.

Example

Assume you have 10,000 USDT in your derivatives account and open a position using 1,000 USDT as margin.

If the market moves against your position:

• Under Isolated Margin, the position would be liquidated once the allocated 1,000 USDT is exhausted.
• Under Cross Margin, the position may continue to draw support from the remaining 9,000 USDT in your account.

This could:

• Prevent liquidation
• Give the market more time to recover
• Allow the position to return to profitability if the market reverses

However, it also increases overall account risk because a losing position can consume your entire account balance.

Comparison of Isolated Margin and Cross Margin

Summary

Choose Isolated Margin if you:

• Want strict risk management.
• Prefer to limit losses on individual positions.
• Want to protect the rest of your account balance from a single trade.

Choose Cross Margin if you:

• Want maximum capital efficiency.
• Actively manage multiple positions.
• Understand liquidation risks and are comfortable using your entire account balance as collateral.

Before selecting a margin mode, make sure you fully understand how leverage, liquidation, and margin requirements work, as each mode offers different levels of risk and flexibility.
