When the margin ratio (net margin / occupied margin) is under 30%, the system will make forced liquidation.
Therefore, pay attention to your account capital.
Forced liquidation will be executed in the sequence of loss amount, with the biggest-loss order first.
Rules of forced liquidation:
1) Firstly calculate the loss of all the positions (including locked positions), and they will be automatically liquidated from biggest-loss order.
2) If positions suffer equal loss, then they will be liquidated in the principle of First In First Out.
3) If the positions are opened in the same time, then they will be ranked in the sequence of their order number, and the order in the front will be liquidated first.
