1. What is the maximum withdrawal rule of the Classic Portfolio Margin Account?
The Classic Portfolio Margin Account withdrawal rules are as follows:
- For single coin withdrawals, you cannot exceed the coinâs wallet balance. You can use the following APIs to check the respective wallet balance: Cross Margin Wallet (spotAsset), USDâ-M Futures Wallet (futuresAsset_UM), COIN-M Futures Wallet (futuresAsset_CM).
- Maximum withdraw amount (calculated in USD) can not exceed âEquity - 1.2 * MM; Maxwithdraw = max (account Equity - 1.2 * MM, 0)
- You can only submit one withdrawal request in the Cross Margin, USDâ-M Futures, and COIN-M Futures Wallets. You cannot submit a second request before the system confirms the first one.
Please note that if the collateral rate of the asset is zero, you can withdraw all of the assetâs wallet balance.
2. What is the maximum loan rule of the Classic Portfolio Margin Account?
The Classic Portfolio Margin Account loan limitation is as follows:
- VirtualMaxLoan = (Leverage - 1) * max (Maxwithdraw - 1 / (Leverage - 1) * VirtualSpotLoan, 0)
[VirtualSpotLoan: USD value of all loan assets in this account]
- MaxLoan = min (VirtualMaxLoan / assetIndexPrice, MaxBorrow - CurrentLoan)
[MaxLoan: max loan by asset value]
3. Can I modify existing orders?
Currently, the Binance Classic Portfolio Margin Program does not support COIN-M Futures API order modification.
4. Can asset balance be negative?
Yes, you can have a negative balance on your Cross Margin, USDâ-M Futures, and COIN-M Futures Wallets as long as your uniMMR does not fall under the liquidation threshold (105%). Auto-exchange does not apply in the Classic Portfolio Margin Account.
For example:
You have a balance of 200,000 USDT in the USDâ-M Futures Wallet, and an ETH short position in COIN-M Futures.
- Letâs assume the ETH price goes up, incurring a loss in your short ETH position, and resulting in a -10 ETH negative balance in the COIN-M Futures Wallet after closing your short position.
- Your new wallet balance would then be 200,000 USDT in the USDâ-M Futures Wallet and -10 ETH in the COIN-M Futures Wallet, with a uniMMR over 105%.
- To offset the negative balance, you need to transfer 10 ETH from the Spot Wallet to the COIN-M Futures Wallet.
5. Can order placement trigger liquidation? What if I place an order with a wallet balance of 0?
Placing an order will not impact the uniMMR. However, order filling/execution will impact the uniMMR and may take it under 105%, which would automatically trigger the liquidation process. You can refer to the dedicated FAQ section for more details about uniMMR calculation.
*For fat finger errors:
As there is no initial margin check, you can still place a market order when your equity balance equals zero. If it triggers liquidation and leads to a negative balance, you shall be solely liable for the deficit.
6. Is Spot Wallet included in the Classic Portfolio Margin Account?
No. Currently, the Binance Classic Portfolio Margin Account only includes Cross Margin, USDâ-M Futures, and COIN-M Futures Wallets.
7. Do the Margin Wallet loan/borrow rules apply under the Binance Classic Portfolio Margin Program?
Loan rules on the Cross Margin Wallet remain effective under the Binance Classic Portfolio Margin Program. However, borrowing fees apply even if the borrowed amount on the Cross Margin Wallet is offset by the equity in the USDâ-M Futures and COIN-M Futures Wallets.
8. Can partial liquidation occur under the Binance Classic Portfolio Margin Program?
Partial Liquidation (closing positions gradually in ascending order) does not apply under the Binance Classic Portfolio Margin Program. Once liquidation is triggered, the liquidation process will not stop until it is completed.
9. What is the actual equity (âactualEquityâ) of the Classic Portfolio Margin Account?
âactualEquityâ is the userâs account equity without collateral rate, calculated as follows:
actualEquity = â(marginAsset - marginLoan + futuresAsset + futuresUnrealPnL) * assetIndexPrice
Please note that "actualEquity" is expressed in USD.
