The amount of foreign exchange purchased will not be displayed until the inventory fee for foreign exchange purchase becomes 0. There are two kinds of inventory fees, one is called the bill-paying inventory fee, and his twin brother sells the bill-paying inventory fee. Although the names of the two brothers are similar, the prices are different. In foreign exchange transactions, the inventory costs of different commodities and the same commodity are different. Inventory expense is not based on inventory management table. According to the calculation of holding positions for 24 hours, China usually closes at around 6 a.m. Beijing time. That is to say, even if I come in at 5: 59 and charge overnight interest at 6: 00, I still have to pay overnight interest. Overnight interest is varied, some charge overnight interest, some are zero, and some banks will pay you overnight interest.
