There is no need to add margin for profit, and there is no need to add margin for loss. Only when the loss exceeds your available funds will you be asked to deposit.
For example, if you have an account of 65,438+10,000 yuan, 80,000 yuan has opened 8 lots of bulls of a certain variety, that is, the opening price of this variety is 10000 yuan, leaving 20,000 yuan of available funds. The variety is 10 ton/hand.
1. After you open a position, the variety rises, and the settlement price is 10500 yuan. Then, your daily profit is: 500 *10 * 8 = 40,000 yuan. This 40 thousand yuan has been transferred to your futures account, but you can't withdraw it.
Because at this time (usually after 5 pm), the trading software of futures companies should not be connected. However, the money can still be raised the next morning. Whether to put it forward specifically depends on personal circumstances.
2. After you opened the position, the variety declined.
A. The settlement price is 9500 yuan, so your loss on that day is: 500 * 10 * 8 = 40000 yuan. And you only have 20 thousand yuan available, then the futures company will inform you of the additional margin, at least 20 thousand yuan. If you don't add, then your position will be tied; Different futures companies have different ways to deal with it, some are all flat, and some are only flat until your available funds are positive.
B, the settlement price is 9900 yuan. Then, the loss of that day: 100* 10*8=8000 yuan, which is less than your available funds. This 8000 yuan will be deducted from your 20 thousand yuan. In the "margin monitoring center", the available funds are only 1.2 million yuan.
