People in the stock group led me to trade on TFBO, giving reverse order advice to cause losses

TFBO platform website: www.xguniversal.com
On October 29, 2018, I added QQ number 287593**** , and then was invited into the QQ group. The group number was (69031**** entry time was November 1, 2018, and the group was dissolved on December 5, 2018) .
Later, a stock conference was organized in the group. And four people competed in stock trading. The website name: Daqian Capital, link: http://cf.vivsd.com/2000, and now it is no longer accessible.
The conference had been held for on month, they said that the stock is not good, and recommended to invest in index. They invited TFOB’s account opening commission into the group. We opened accounts by sanding he information. the trading software is MT4, the trading server is SunriseGrandintl-live.
The previous orders were somewhat profitable. After they gave malicious advice, we suffered a major loss. Through our own understanding of the market, some of the orders did not be made, but the accumulated losses were still around 106,000 yuan.
On December 5, 2018, the new group was created (70590****) . Since the last message was released on December 12, no information was released. Now the MT4 software account can't be logged in. Fortunately I sorted all the chat records, transfer records, and transaction records before the complaint.
