1, futures short position refers to the state that the funds in the account are zero due to insufficient margin in futures trading, and the floating profit and loss in the account >; = When all the funds in the account are available, the futures trader forcibly closes the position. This situation is called explosion. For example, a customer uses leverage of 10 to buy 1 hand futures products, and the margin is 10 yuan. Due to leverage, the value of this 1 hand futures is 100 yuan. If 1 futures is in the opposite direction, resulting in a continuous loss of the user's margin 10 yuan, and finally a negative 10 yuan situation, then the futures company will forcibly close the position and sell it. At this time, the user's account has exploded.

2. Empty positions are often related to many aspects. For example, the leverage of the transaction is too high, the market changes too fast, and there is no stop loss line. These aspects may lead to the emergence of short futures. Of course, when the account status is about to explode, users can also choose to continue to add margin to maintain the current account status. However, this is a risky practice, and if the market continues to go bad, it may cause greater losses.
