In the futures market, strong balance and short position are two different concepts. Strong flat refers to being forced to close the position by the futures company, not my will. Generally speaking, there are two main reasons for the strong level. One is strict losses and insufficient margin. Futures companies have reminded investors to add margin, but investors have not added it for various reasons. At this point, the position will be forced to close the position. The other is a violation of trading rules. For example, some futures do not support individuals to enter the delivery month, but some investors do not understand or ignore its delivery time, and inadvertently enter the delivery month, and will be forced to close their positions. In addition to these two reasons, sometimes sudden changes in policies may be forced to equalize.

As one of the futures terms, warehouse penetration refers to the risk that the customer's rights and interests in the customer's account are negative, that is, the customer not only lost all the margin in the account before opening the position, but also owed money to the futures company. There are two kinds of risks closely related to forced liquidation: puncture and abandonment. The so-called warehouse penetration refers to the risk that the customer's rights and interests in the customer's account are negative, that is, the customer not only loses all the margin in the account before opening the position, but also owes money to the futures company. In the case that futures companies strictly implement the debt-free settlement system on the same day, cross-position events are not common, but they are also heard from time to time, because in the case of violent market fluctuations, customers' positions may be blocked on the stop-loss board quickly. If the next day, under the action of inertia, the market opens sharply, and the customer is in Man Cang the day before, there may be a warehouse-breaking event.

The concepts of warehouse penetration and warehouse explosion are the same. For example, if the loss is too serious to close the position or the strong flat directly touches the warehouse explosion line, the order will directly penetrate the position and then be forced to close the position. At this time, the consequences of forced liquidation are more serious, the general principal has been completely lost, and the probability of owing money to the futures company is greater. Then as an investor, you must pay back the money within the specified time. If it is overdue, it will be sued by the futures company, so it is much more serious than the strong warehouse.

It is worth pointing out that after the stock index futures simulation trading begins, the media sometimes report that "customers can still trade xx million", and the penetration described here is not true, because these media mistakenly regard the situation that the available funds of customers are negative in the stock index futures simulation trading as penetration, and at this time, the customer's rights and interests are still positive, but the available funds are negative, and there is no penetration.
