The teacher in the Line group is luring members to deposit into platform and advocating the foreign exchange of XAUUSD. Each transaction results in a high profit rate of return, but at the same time, the real-time quotation is checked with a licensed foreign exchange platform, and it can be found that this is a fake platform. The price of XAUUSD was clearly falling, but the group teacher made people buy it up, and then the closing price went up, but the actual XAUUSD price actually fell, causing the members in the group to think that the teacher was really good at it, but the quotation was actually changed by them to let more members to invest. In the pircture, there is position opening time and price. The closing price is 1946, but it is actually less than 1940.
