When the main contract of commodity futures is approaching delivery, some funds will use their capital advantage and spot advantage to do some operations in the market, forcing retail investors who do the wrong direction to stop losses and make a big profit.

Forced liquidation refers to the trading behavior that one party uses the advantage of funds or warehouse receipts to guide the market to move unilaterally, resulting in the other party's continuous losses, and finally has to cut its position. Generally divided into two forms: forced empty warehouse and forced empty warehouse.
