If you set a stop-loss or take-profit order, when market price fluctuations reach the stop-loss price or take-profit price you set, the system will automatically close the position according to the order. In addition, when the margin ratio of your account is lower than the warning line of 150%, the system will close the current open positions starting from the position with the most losses. When the margin ratio is equal to or lower than 100%, the system will force all open positions to be closed.
