In this March,I knew that a teacher named Chen he who gave free lessons on stock trading on the internet.I added him and was pulled into a lesson-giving platform named Huixintianxia.I have listened to lessons for 2 months,during which I bought some stocks,earning some money. Then he recommended the MT4 platform of FDEX,saying that profits can be made both in going up-and-down market instead of in a rising market.With the customer service’s instruction,I installed the APP and opened an account,depositing some money into it.Operating on some orders,I made some profits.With his induction of more profits,I deposited $60000 in all.On April 30th,I placed an order of second-hand China 50,without closing position.After May Day,ma account became forced liquidation,owing $17000.When I contacted him,he said that the losses were caused by my improper operation,without setting the stop-loss price.After that,he was out of contact.I called the police on May 9th. Hope you raise your vigilance and avoid being cheated by this platform!!!!
