In addition, there will be monitoring at closing time every day. For example, at 5: 00 this morning, a customer made multiple lots of 1 and the net value was less than 10000 (for example, there was still 9000), so the customer would be informed during the day, and the position would be closed by himself before 5: 30 pm, or the margin would be added. After 5: 30, the margin is not enough, and the customer will be forced to close the position, taking 0.5 lots as the unit. If the margin is sufficient, the position will not be closed.
