The account is maliciously suspended and cannot withdraw

A few days ago, fluctuation is fast and I will be liquidated if I do not close the position for 100 times leverage. I did not trade a lot and they suspend my accoutn when there is a huge fluctuation. There is no warning about high-frequency trading. I do not want to trade at here anymore. That is why people do not want to trade at here. It becomes worse and worse.
