How do I calculate the maximum amount that I can transfer in/out in Cross and Isolated Margin modes?

Pro Mode (Orderbook Trading)

Cross Margin Mode:

When your wallet balance is not being used for cross collateral, you can use the following two formulas to calculate your maximum amount in Cross Margin mode:

• Cross Wallet Balance — ∑ Isolated Open Position Initial Margin — Cross Position Maintenance Margin

For wallets with Unrealized PnL, the maximum withdrawal amount must not exceed the following formula:

• Cross Wallet Balance + Σ Cross Unrealized PnL — Σ Cross Initial Margin — Σ Isolated Open Position Initial Margin

Isolated Margin Mode:
