1. Loan and Repayment
Under automatic mode, users do not need to make loan/repayment manually. The system will judge whether the user needs to make loan or not based on his available asset and order amount. If the order amount is greater than the user's available asset, the system will make loan automatically and the interest will be counted immediately. If the order cancelled or partially filled, the system will repay the loan automatically to avoid the interest generated by the idle loan.
2. Maximum tradable amount
Under automatic mode, the system will display the maximum tradable amount to users based on the leverage times and user's net asset in the margin account (Max. tradable amount = Net asset + Max. loan amount).
3. Unpaid Loan
Under automatic mode, if user has unpaid loan, the system will first repay the loan and interest when the user transfer the corresponding asset into margin account. The interest will first be repaid then the principal. Besides, users are unable to switch trading mode if there's loan unpaid. At the moment, users can click "close position" to repay the loan. Then, the user can try again.
