Interest Calculation
1. Interest will be collected if the liability is generated in cross margin and isolated margin mode. However, in the multi-currency and portfolio margin account cross position , the unrealized loss generated by the derivatives positions will enjoy an interest-free limit, and if the liabilities caused by the unrealized loss amount of the derivatives positions is within the interest-free, no interest will be accrued.
2. Interest calculation and deduction
The interest of the liabilities in cross margin mode and isolated margin mode will be calculated and deducted respectively;
The interest is calculated and recorded every hour, and is deducted every hour based on 16:00(UTC). It’ll take around 10 minutes to record accrued interest. Any liabilities that are incurred during this period will be recorded as well.
Example: When a user borrows money at 14:55, user interest is not recorded at this time. At 15:00, the user's interest is calculated through liabilities. At 15:00, interest deduction occurs. If the user pays off the borrowed currency at 14:57, interest will not be accrued.
