There is a loophole in the EX background application for demo accounts, causing many salespersons in the market to cheat and deceive using this loophole! For example, after a salesperson applies for a demo account, on the first day of deposit, they will first set a deposit of 10 million, and on the second day, they will deposit another 5,000 USD. From the second day onwards, the trading interface will have both long and short positions for the same product, closing profitable trades and leaving losing ones open. Because there is a base position of 10 million, it will never be liquidated. Then, starting from the second day's deposit, the trading record shows a challenge of making a profit of 1 million from 5,000 USD. At the same time, EX demo also allows setting withdrawals, so the fabricated trading records look very realistic. Many salespersons use these trading records to attract clients to other platforms through media posts or WeChat, then violently churn commissions. Many investors in the market have been deceived. I am also a victim. I hope the platform can close the demo account's ability to freely set deposits and withdrawals at any time.
