The first is the automatic liquidation caused by the expiration of futures products. Many products in the market belong to futures products, such as crude oil and bonds. These products have fixed trading hours. If the investor does not close the position during this period, the platform will automatically close the position on the maturity date, regardless of the profit and loss of the position.

The second is the automatic liquidation caused by insufficient margin. Some products, such as foreign exchange and gold, are international spot transactions and adopt leveraged trading mode. Investors need a certain margin when trading. When the price fluctuates, the profit and loss come from the remaining funds in the investor's account. If the remaining funds cannot bear the risk of price fluctuation, it will lead to automatic liquidation. To put it simply, this situation is that the account has no money, which is also called short position. Investors must be careful.

Third, automatic liquidation caused by other circumstances. For example, investors set a stop loss when trading, and if the price falls to their own stop loss price, it will trigger automatic liquidation. For another example, if the investor has set a take profit, if the price rises to its own take profit price, it will also trigger automatic liquidation. There are many similar situations.
