First of all, we should understand that the available funds in the account can be negative, but most of this will happen in the actual transaction process, that is to say, the total amount of funds in the customer's account MINUS the margin occupied by opening positions may be negative after deducting the loss of positions. We must understand this situation, and in this case, the customer's funds are not enough to cover the support level, occupy the margin and lose the position, so in real life, we have a lot.
In addition, we can clearly know that in the case of short positions, our funds may also be negative, and the reason for short positions is that in this case, customers must use money to make up their debts, otherwise they will bear corresponding legal responsibilities, and short positions are basically difficult to meet in real life, unless a futures encounters rare circumstances or suffers huge losses. There will be a situation in which users explode their positions, but once there is an explosion, basically our investors will face huge losses and even bring huge economic losses.
To sum up, we can clearly know that the funds in our account may be negative, so in real life, we should solve this problem well. When investing in futures, we should also pay attention to not investing rashly and learn relevant theoretical knowledge.
