I earned 150 thousand dollars by trading DJI. On March 13rd, I wanted to make a withdrawal of 50 thousand RMB, while there was only $2000 left in my account on the next morning. Having checked the record, I figured out that there were more than 100 orders placed on XAG/USD during 00:18 to 00:28, with each being held for only 1 to 2 seconds. Thus, my 150 thousand dollars was gone. Take heed on it.
