The Classic Portfolio Margin Account has streamlined the fund transfer features to improve user experience. You can use the new Aggregate balances and Auto-repay to better manage your funds.
1. Asset transfer logic between different Portfolio Margin wallets
Transferring funds between different wallets is an essential aspect of managing your Classic Portfolio Margin Account. The Classic Portfolio Margin Account supports transfers between the Margin-PM and Futures-PM Wallets, as well as between the PM wallets and other Binance wallets. Please note that certain restrictions apply.
Portfolio Margin wallets transfer rules:
- You can only transfer assets in and out of the Classic Portfolio Margin Account through the Margin-PM Wallet. Please note that transfers in and out of the USDâ-M or COIN-M Futures-PM Wallets to non-PM wallets (such as the Spot and Options Wallets) are not supported.
- You can only transfer assets from the Futures-PM Wallets to the Margin-PM Wallet using the Aggregate Balances function within the Classic Portfolio Margin Account (except for BNB in the USDâ-M Futures-PM Wallet).
- Transfer of assets from Margin-PM Wallet and USDâ-M and COIN-M Futures-PM Wallet are not allowed, with the following exceptions:
- BNB can be moved from Margin-PM Wallet to USDâ-M-PM wallet for trading fee discounts on Futures.
- If Auto Repay is activated, manual repayment from Margin-PM to either USDâ-M-PM or COIN-M-PM Wallets is allowed for a specific asset until its negative balance is restored.
- USDâ-M and COIN-M Futures-PM Wallets cannot transfer assets to one another.
2. What is the Transfer BNB function?
Using the Transfer BNB function, you can transfer BNB from your Margin-PM Wallet to your USDâ-M Futures-PM Wallet to enjoy BNB trading fee discounts on Futures trading.
Please note that you can only use this function ten times per a rolling 10-minute period.
Please note that you can only use this function ten times per a rolling 10-minute period.
3. What is the Aggregate balances function?
The Aggregate balances function simplifies the fund transfer process between different wallets and reduces potential errors associated with manual transfers.
When you click the [Aggregate balances] button or send an API request, the system will automatically transfer all positive balances from your USDâ-M and COIN-M Futures-PM Wallets to your Margin-PM Wallet.
Please note that your BNB in the USDâ-M Futures-PM Wallet wonât be automatically transferred.
Note: For API support specifications, please refer to the Fund Auto-collection part of the API documentation on Github.
4. How to activate the Aggregate balances function?
Log in to your Binance account and mouse over the wallet icon. Click [Margin/Futures] - [Transfer].
Click [Aggregate balances], and all your positive balances will be transferred to your Margin-PM Wallet.
Please note that the [Aggregate balances] function will only be available when you transfer from the Portfolio Margin Wallet to the Fiat and Spot Wallet, as shown below.
API details:
- Please note that you can use the aggregate balance feature via API via the POST /sapi/v1/portfolio/auto-collection endpoint.
- For more granular control over fund collection, you can use the POST /sapi/v1/portfolio/asset-collection endpoint to query fund collection on a per-asset basis.
5. What is the Auto-repay function and how does it work?
The Auto-repay function can automatically repay your negative balances in the USDâ-M and COIN-M Futures-PM Wallets by transferring the corresponding assets from your Margin-PM Wallet, provided that you have the same assets in your Margin-PM Wallet. No auto repayments will occur if you donât have the required assets in your Margin-PM Wallet. In this case, you need to manually transfer the assets into your Margin-PM Wallet to allow the auto-repay process to operate.
Schedule
The Auto-repay function operates twice a day, within 2 hours before charging the negative balance interest. The daily interest charge time is 00:00 (UTC).
The Auto-repay function operates twice a day, within 2 hours before charging the negative balance interest. The daily interest charge time is 00:00 (UTC).
For example, if the system auto-repays 50% of your BTC negative balance at 22:50 and 23:45 (UTC) and you transfer more BTC into your Margin-PM Wallet at 23:50 (UTC), the system wonât auto-repay again on the same day (as the function only operates twice a day).
Limitations
Auto-repayment only happens from the Margin-PM Wallet to the USDâ-M or COIN-M Futures-PM Wallets. This means your USDâ-M and COIN-M Futures-PM Wallets cannot automatically repay each other's negative balances.
For example, if you have a positive BTC balance in the COIN-M Futures-PM Wallet and a negative BTC balance in the USDâ-M Futures-PM Wallet as a result of trading ETHBTC USDâ-M Futures contract, auto-repayment cannot occur. In this case, you must manually transfer BTC from the COIN-M Futures-PM Wallet to the Margin-PM Wallet using the Aggregate Balances function. After that, auto-repayment can occur from the Margin-PM Wallet to the USDâ-M Futures-PM Wallet.
6. What are the benefits of the Auto-repay function?
The Auto-repay function offers several advantages, including:
- Simplified fund management: Automated transfers between wallets reduce the need for manual intervention and simplify account management.
- Reduced risk of errors: Automated transfers help minimize errors during fund transfers.
7. What are the limitations and rules of the Auto-repay function?
Enabling or disabling the Auto-repay function
The Auto-repay function is activated by default. You can choose to deactivate Auto-repay and switch to Manual Repay from the [Futures] interface, as shown below:
Notes:
- If you disable Auto-repay and have a negative asset balance in your USDâ-M-PM or COIN-M-PM Wallets, you must manually transfer assets from Margin-PM to either USDâ-M-PM or COIN-M-PM Wallets.
- When Auto-repay is activated, manual repayment of assets from Margin-PM to either USDâ-M-PM or COIN-M-PM Wallets is allowed for a specific asset until its negative balance is restored.
Interest charges
Please note that negative balances in the USDâ-M and COIN-M Futures-PM Wallets may incur interest charges. However, there is an interest-free threshold for each asset (refer to the table under point 9 for the threshold per asset)
Repayment order
The Auto-repay function will repay the negative balances in your USDâ-M or COIN-M Futures-PM Wallets in no particular order. For example, you have negative balances in your USDâ-M and COIN-M Futures-PM Wallets after trading BTC-Margin contracts. The Auto-repay function will perform repayments in a random order.
8. Negative balances and interest rates in the USDâ-M and COIN-M Futures-PM Wallets
"NegativeBalance" for a particular asset occurs when the combined balance of free assets (reflected as âavailable balanceâ) in the Margin-PM, USDâ-M Futures-PM, and COIN-M Futures-PM Wallets is negative, indicating a deficit in that specific asset. It is calculated independently with a specific negative balance threshold for each asset.*
You can have a negative balance on your USDâ-M and Coin-M Futures-PM Wallets, as long as your uniMMR remains above the liquidation threshold (105%).
If your negative balances exceed the threshold, youâll be charged an interest fee once a day at 00:00 (UTC). This interest fee is calculated based on your Margin Loan's daily interest rate and the negative balance's absolute value. Please note that if you have the required assets in your wallet, the system will automatically attempt to repay your negative balances within two hours before the interest charge.
Please note that Auto-exchange does not apply to the Classic Portfolio Margin Account.
To calculate the interest fee:
interestFee = abs(negativeBalance) * dailyInterestRate
negativeBalance = min(totalAssetBalanceAcrossPMWallets + negative_threshold,0)
Where:
- âinterestFeeâ is the fee charged for having a negative balance;
- ânegativeBalanceâ is the account balance when it is negative (below zero);
- "NegativeBalance" for a particular asset occurs when the combined balance of free assets (reflected as âavailable balanceâ) in the Margin-PM Wallet and assets in the USDâ-M and COIN-M Futures-PM Wallets is negative, indicating a deficit in that specific asset. It is calculated independently with a specific negative balance threshold for each asset.*
- âdailyInterestRateâ is your Margin Loanâs daily interest rate;
- ânegative_thresholdâ is the negative balance threshold in the negative balance threshold table.
For example, if your negative balance is -10,050 USDT and the daily interest rate for your Margin Loan is 0.1%, the interest fee would be:
interestFee = abs(-50) * 0.001 = 0.05 USDT
*For instance, if your BTC balance is negative in the USDâ-M Futures-PM Wallet, but is counterbalanced by a positive BTC balance in the COIN-M Futures-PM or Margin-PM Wallets. It will result in a net positive overall BTC balance in the Portfolio Margin supported wallets. "NegativeBalance" for BTC will not apply and, consequently, no interest will be charged.
