**How to calculate the maximum addable/removable margin in Cross and Isolated margin modes?**

**Cross Margin Mode:**

Users can use the two formulas below to calculate the maximum withdrawal amount when your wallet balance has not used cross collateral:

- CrossWalletBalance - ∑Isolated Open Order Initial Margin - Cross Position Maintenance Margin

- CrossWalletBalance + ∑Cross Unrealized PNL - ∑Cross Initial Margin - ∑Isolated Open Order Initial Margin

**Isolated Margin Mode:**

Formulas for calculating the maximum addable and maximum removable margin of USDⓈ-Margined contracts:

- Max addable amount to isolated margin:

min（CrossWalletBalance - ∑Isolated Open Order Initial Margin - ∑CrossPosition MM, Available for Order）

- Max removable from isolated margin:

max（0，min (IsolatedWalletBalance - IsolatedPosition MM, IsolatedWalletBalance + size * (Mark Price - Entry Price) - Mark Price * abs(size) * IMR)）
