Stock index futures are settled daily. Today, even if the equity "increases" to a negative number, it will not be forced to close the position. Just make up the deposit before the transaction tomorrow. This question is a bit difficult. If the intraday losses are really severe, it is very likely that futures companies will be forced to close their positions when they reach the bottom line. It is impossible for futures companies to bear this risk for investors.

Forced liquidation generally includes two situations:

1. If the account margin is insufficient, the margin monitoring center will notify the futures company and then go to the individual. If the margin cannot be replenished within the specified time, and the margin balance is less than 0, the monitoring center will take compulsory liquidation, and the amount of liquidation will be sufficient until the margin is greater than 0.

For example, if the margin account has 100w, and you open a position and buy four long positions, then the contract will occupy 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 a loss of 30w, only 70w is left in the margin account. This is the so-called insufficient margin. The futures company will notify to make up the deposit. If you don't make up, you will be forced to level off, which is very easy to calculate. In this example, you can probably level 1 hand.

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 the open position is more than 100 lots, such as 1 10 lots, the margin monitoring center will close the account with 10 lots.
