Hello, forced liquidation is generally when the net value of your account (that is, the total account funds minus floating losses) does not reach the maintenance margin (domestic generally means the trading margin, but abroad generally the maintenance margin is lower than the trading margin) When the time comes, you will be asked to add margin. When you cannot add funds on time, you will be forced to close the position.

Liquidation means that your account is already in a loss-making state, and the system will forcefully close the position and you will no longer be able to trade
