How to calculate the maximum addable/removable margin in Cross and Isolated Margin Modes?

Cross Margin Mode

The following calculations are the maximum withdrawal amount in Cross Margin Mode. The two formulas apply when your wallet balance has no gift money or has not used cross collateral:
  • crossWalletBalance - ∑Isolated Open Order Initial Margin - Cross Position Maintenance Margin
For wallets with unrealized profits or losses, the maximum withdrawal amount must not exceed the following formula:
  • crossWalletBalance + ∑Cross Unrealized PNL - ∑Cross Initial Margin - ∑Isolated Open Order Initial Margin

Isolated Margin Mode

The following are calculations for the maximum addable and removable margin:

USDⓈ-Margined contracts

Field
Calculation
Max addable amount to Isolated Margin
max (0, min(crossWalletBalance - ∑isolated open order initial margin - ∑crossPosition MM, Isolated Available for Order))
Max removable amount from Isolated Margin
max (0, min (isolatedWalletBalance - isolatedPosition MM, isolatedWalletBalance + size * (Mark Price - Entry Price) - Mark Price * abs(size) * IMR ))

COIN-Margined contracts

Field
Calculation
Max addable amount to Isolated Margin
max (0, min (crossWalletBalance - ∑Isolated Open Order Initial Margin - ∑crossPosition MM, Isolated Available for Order))
Max removable amount from Isolated Margin
max (0, min (isolatedWalletBalance - isolatedPosition MM, isolatedWalletBalance + size * contractSize * (1 / Entry Price - 1 / Mark Price) - abs(size) * contractSize * IMR / Mark Price))
