I am trading on the Doo Prime platform (https://user.dooprime.net/），入金1.1万美金，赚取了8000美金，然后客服说我交易违规，不准我出金。具体经过截图如下，然后平台工作人员各种推诿。事情已经过去7天没有得到任何实质性回复。 The details are as follows: Hello, I am a Doo Prime customer with account: F9708457, registered email: 2858219456@qq.com. Yesterday (around 17:00 Beijing time on 20260714), I received an email from your company stating that my normal withdrawal request was rejected and that there are pending deductions. I am confused about your platform's actions: The following are the points I would like the platform to explain: 1: The exemption of overnight fees is a welfare policy provided by your platform. It complies with your platform's regulations. 2: USDTRY (US Dollar/Turkish Lira) and EURTRY (Euro/Turkish Lira) are two products that your platform allows trading. There is no indication that holding positions or placing orders is prohibited. If the platform had explicitly stated that these products cannot be held or purchased, it could have made them untradeable like other platforms do. Since the platform has not restricted trading in these two products, why can't traders buy them? 3: All purchased products have been held for more than 3 days, and there is no hedging or arbitrage operation. Based on the above three points, traders bought USDTRY and EURTRY on the DOO platform and held positions. The platform also previously provided traders with the welfare support of the interest-free policy, which is reasonable and compliant. Yesterday (around 8:00 Beijing time on 20260714), DOO platform staff said they would retroactively charge overnight fees for previously held positions. What is the reasoning? 1: If USDTRY and EURTRY cannot be purchased, why can they be freely traded on the DOO platform? 2: If overnight fees are to be retroactively charged, why was the welfare of exempting overnight fees previously granted to traders? 3: If the platform claims that traders engaged in arbitrage or hedging operations, please provide evidence. 4: If the platform has changed the rules to indicate that USDTRY and EURTRY are products that are not exempt from overnight fees, then it should be based on the time of staff notification or platform announcement. The platform notified through customer service at around 8:00 Beijing time on 20260714. As traders, we would fully understand the new rules and adjust our positions accordingly after receiving the notification. Why does the platform still retroactively charge overnight fees for previously held positions?
