Cross Margin Mode Overview

  • Updated

What Is Cross Margin Mode?

In Cross Margin Mode, supported collateral assets in your account are shared across your open positions. This means your total account equity is used to support all active trades, allowing profits from one position to help cover losses from another.

Note: Multi-position mode is allowed under cross-margin mode.

 

Key Features

Account Equity: The total value of your assets used as collateral, calculated as:
Account Equity = Sum of (Collateral × Collateral Value Ratio) + Unrealized P&L

Account Maintenance Margin: The minimum collateral required to maintain all open Cross Margin positions.

Account Margin Ratio: Measures your account-level risk:
Cross Margin Ratio = Account Maintenance Margin​ / Account Equity

Actual Leverage: The effective leverage used across all positions in your Cross Margin account.



Multi-Asset Mode Enabled by Default

When Cross Margin Mode is active, Multi-Asset Mode is automatically enabled. This allows multiple supported assets — such as BTC, ETH, USDT, USDC, USDe, PUSDT, and Flipster Bonus to be used as shared collateral for your open positions.

Example:
- If your account holds a BTCUSDT perp position and 0.01 BTC (worth 1,000 USDT), 0.2 ETH (worth 500 USDT), both assets contribute to your overall collateral balance.
- And if your BTCUSDT perp position moves against you and loses more than 1,000 USDT, your ETH and BTC collateral can help cover the shortfall.
- This mechanism helps reduce the chance of immediate liquidation, but it also means that losses from one position can affect the collateral of all others, exposing your entire margin account to shared risk.

 

Adding Margin

  • Cross Margin automatically uses your supported assets in the account to maintain margin for all positions.
  • Manual margin adjustment is not available for individual positions in Cross Margin Mode.

     

Liquidation Rules

Cross Margin positions are managed at the account level, and liquidation follows these rules:

  1. A warning email is sent when your Account Margin Ratio is ≥ 90%.
  2. Liquidation is triggered when the Account Margin Ratio is ≥ 100%.
  3. Liquidation process:
    1. All open orders are canceled.
    2. If canceling orders is insufficient, all positions in the account are liquidated.

This ensures that losses do not exceed your total account equity.
