1. If the margin in your account is insufficient, the margin monitoring center will notify the futures company and then find someone. If you can't make up the margin within the specified time and the margin balance is less than 0, the monitoring center will take compulsory liquidation for you until you can ensure that your margin is greater than 0.

For example, if the margin account is 100w, and you open a position and buy four long positions, the contract will take up about 80w of margin. On April 9 19, the stock index fell by 250 points, 1 point 300 yuan, and the four contracts lost 30w. At this time, if the four contracts are not closed, it will take about 80w to occupy the margin, but after losing 30w, there will only be 70w in your margin account. This is the so-called insufficient margin. The futures company will inform you to make up the deposit. If you don't make up the deposit, you will be leveled. This is easy to calculate. In this example, 1 hand is enough.

2. For futures or stock index futures, investors need to abide by the position limit system to prevent large funds from manipulating the market for personal gain. The position limit of the stock index is 100 lots.

If you open more than 100 lots, such as 1 10 lots, the margin monitoring center will close your account 10 lots.
