Strong leveling occurs in two situations:

1. The first situation is also common, that is, there is a loss in the position and the funds may be negative. Futures companies will notify investors to add margin. If investors replenish on time, they can continue to hold positions. If investors don't add margin in time, they will be forced to close their positions. Will it be forced to close the position at this time? No, it will only flatten the positions of some investors who do not have enough margin positions, that is, only until the available funds are greater than zero.

2. In the second case, the position violates the rules and enters the trading month. If it is a variety that cannot enter the trading month, the futures exchange will force the liquidation. Note that the profit of futures exchange positions belongs to the exchange, and the loss is borne by investors. Therefore, investors should pay attention to avoid this situation.
