Futures liquidation can be divided into active liquidation and forced liquidation. Among them, active liquidation means that investors can sell as long as they are trading, and passive liquidation means that the platform helps investors sell. Generally speaking, when the investor's margin is below a certain level, the platform will force investors to close their positions in order to reduce losses. The margin of different futures products is different. For example, the margin ratio of soybeans is 10%.

Futures liquidation refers to the behavior of futures traders to buy or sell futures contracts with the same variety code, quantity and delivery month but opposite trading direction, and then liquidate their positions.
