How to Calculate Margin Ratio in the Multi-Assets Mode?

How to check your account margin ratio under the Multi-Assets Mode?

If you select the [Multi-Assets Mode], you'll see a [Multi-Assets] tag on the Margin Ratio widget.

Since your margin balance is shared across multiple positions in the Multi-Assets Mode, please monitor your margin ratio closely. Once the margin ratio reaches 100%, all positions will be liquidated.

How to calculate margin ratio in the Multi-Assets Mode?

You can use the following equation to calculate your margin ratio in the Multi-Assets Mode:

Account Margin Ratio = Account Maintenance Margin / Account Equity

Account Maintenance Margin = Sum of Maintenance Margin of All Cross Positions (in USD)
Account Equity = Sum of Margin Balance of All Cross Positions (in USD)

Please note that the margin ratio is based on the prevailing market rate for USDTUSD and USDCUSD pairs.

Example

Suppose the asset pairs and their respective floating conversion rates are as follows:

Asset Pair	Asset Index	Index Bid Buffer	Index Ask Buffer	Bid Rate	Ask Rate
USDTUSD	0.99	0.01	0.005	0.9801	0.99495
USDCUSD	1	0	0	1	1

You want to trade two contracts, BTCUSDT perpetual and ETHUSDC with 100x and 50x leverage respectively. In this scenario, the Maintenance Margin Ratio will be 0.8% and 1% respectively. Depending on the margin mode you’re (Isolated or Cross), the account status and calculation changes of various parameters are as follows:

1. Initial state - No open positions

Symbol	BTCUSDT	ETHUSDC
Margin Asset	USDT	USDC
Asset Wallet Balance	200	220
Asset Equity	200	220
Maintenance Margin Ratio	0.008	0.01
Initial Margin Ratio	0.01 (100x)	0.02 (50x)
Unrealized PnL	0	0

Under the Single-Asset Mode:

USDT available for order = 200 USDC available for order = 220

Under the Multi-Assets Mode:

Account Equity = ∑min(assetEquity*bidRate, assetEquity*askRate) = 200 * 0.9801 + 220 * 1 = 416.02

As there are no open positions,

assetCrossInitialMargin = 0
uniAvailableForOrder = accountEquity-∑(assetCrossInitialMargin*askRate) = 416.02 - 0 = 416.02
USDT Available for Order = 416.02 / 0.99495 = 418.13
USDC Available for Order = 416.02 / 1 = 416.02
Account Maintenance Margin Ratio = 0
Margin Ratio = Account Maintenance Margin / Account Equity = 0

2. With open positions

Symbol	BTCUSDT	ETHUSDC
Margin Asset	USDT	USDC
Asset Wallet Balance	200	220
Asset Equity	200	220
Maintenance Margin Ratio	0.008	0.01
Initial Margin Ratio	0.01 (100x)	0.02 (50x)
Position Quantity	0.5	20
Entry Price	20,000 USDT	600 USDC
Mark Price	20,000 USDT	600 USDC
Unrealized PnL	0	0

Account Maintenance Margin = ∑assetMM*askRate = 0.5 * 20,000 * 0.008 * 0.99495 + 20 * 600 * 0.01 * 1 = 199.596

As there is no unrealized PnL,

Account Equity = accountWalletBalance = 416.02
uniAvailableForOrder = Account Equity - ∑(assetCrossInitialMargin * askRate) = 416.02 - (0.5 * 20,000 * 0.01 * 0.99495 + 20 * 600 * 0.02 * 1) = 76.525
USDT Available for Order = 76.525 / 0.99495 = 76.91
USDC Available for Order = 76.525 / 1 = 76.525
Margin Ratio = Account Maintenance Margin / Account Equity = 199.596 / 416.02 = 0.47977 = 47.98%

3. With open positions and unrealized PnL

Symbol	BTCUSDT	ETHUSDC
Margin Asset	USDT	USDC
Asset Wallet Balance	200	220
Asset Equity	200 - 500 = -300	220 + 400 = 620
Maintenance Margin Ratio	0.008	0.01
Initial Margin Ratio	0.01 (100x)	0.02 (50x)
Position Quantity	0.5	20
Entry Price	20,000 USDT	600 USDC
Mark Price	19,000 USDT	620 USDC
Unrealized PnL	0.5 * (19,000 - 20,000) = -500	20 * (620 - 600) = 400

Account Maintenance Margin = ∑assetMM*askRate = 0.5 * 19,000 * 0.008 * 0.99495 + 20 * 620 * 0.01 * 1 = 199.61
With unrealized PnL, Account Equity = ∑min(assetEquity*bidRate, assetEquity*askRate) = -300 * 0.99495 + 620 * 1 = 321.515
uniAvailableForOrder = Account Equity - ∑(assetCrossInitialMargin * askRate) = 321.515 - (0.5 * 19,000 * 0.01 * 0.99495 + 20 * 620 * 0.02 * 1) = -21
USDT Available for Order and USDC Available for Order are both 0
Margin Ratio = Account Maintenance Margin / Account Equity = 199.61 / 321.515 = 0.62084 = 62.08%
