When the available funds are zero or less, you will receive a phone call from the futures company to inform investors to add margin. So when should investors add margin to futures, and when should they add margin at the latest?

Generally divided into two situations.

1, add margin in the session, when the session fluctuates violently.

If investors hold heavy positions and suffer huge floating losses, resulting in insufficient available funds, they need to immediately add margin in the session. Under normal circumstances, futures companies will call investors in advance to make up the margin. If the market was extreme at that time and investors failed to make up the margin within the specified time, the futures company would close the position of investors, so investors would try to close the position manually or make up the funds themselves. Investors will ask, what is a strong flat? Will there be no money after a strong flat?

2. After settlement, additional margin shall be paid for futures settlement.

If the funds available to investors are negative after the market closes, they need to be added before 8: 50 am on the second trading day, and the varieties with night trading need to be added before 20: 50 pm, otherwise they may be forced to close their positions by futures companies, or there is a risk of strong trading during night trading. Futures companies are forced to trade at the market price, so if the account needs to be insured, investors are advised to add margin as soon as possible or handle it by themselves.
