After the futures basic deposit is paid, the deposit will be refunded after the delivery is completed. After delivery and settlement, the deposit will be returned to the futures account, so traders can apply for returning this part of the deposit paid in advance when they end the transaction or perform the contract according to the regulations, and the futures market is no exception. After the trader closes the position, this part of the deposit will return to the account of the futures trader, but the trader will find that this part of the fund may increase or decrease compared with what he paid before, which will cause the problem of profit. If the trader makes a profit and closes the position, the margin will increase. On the contrary, if the trader loses money, the funds will be reduced. Now you can open an account with your mobile phone, and you can also enjoy preferential transaction fees and preferential transaction deposits.
