First of all, we should correctly understand the meaning of short position. Short position means that the loss is greater than the available funds in your account after removing the trading margin, that is, the settlement reserve is less than the loss. At this time, the balance is strong, and after deducting some losses from the occupied trading margin, there may be some funds left in the account. There is also a corresponding word, that is, wearing a position. At this time, the trading margin vacated after the strong contract is still not enough to make up for the loss, resulting in liabilities to the futures company, and the total amount of funds in the account is negative. Generally speaking, warehouse crossing occurs under extreme market conditions, such as the National Day market in 2008. Some commodity futures have been trading for six consecutive days, and they can't run away if they want to.

In this way, if it is Man Cang operation, it means that the settlement reserve is 0. As long as the direction is reversed, even the smallest unit change means an empty position. In other words, as long as the settlement reserve is less than 0, it is an empty position, which has nothing to do with the trading margin you occupy. In the example, 6,543,800+0.2 million belongs to the trading margin, which has been completely occupied. It should be noted here that the trading margin changes with the price. The trading margin occupied by 3000 points and 30 10 points is different, and the margin ratio may change, for example, from 18% to 20%, and the trading margin will also change. As for forced liquidation, general futures companies will call you when your settlement reserve is insufficient, and they also have the right to force liquidation without notice in case of emergency, depending on the contract agreement between you.

As for another question, my understanding of what you mean is, "As long as I don't form debts to the futures company, that is, I don't wear positions, the futures company will not close its positions." In fact, as the risk control of futures companies, short positions are already the basis of their strength. Because in the case of short positions, your trading margin is insufficient, and you can't guarantee the smooth completion of the transaction. You originally needed a deposit of 12w, but because of the loss of 12w, you could not meet the requirements of the transaction.
