RIVER/USDT Perpetual Contract Trading encountered a severe deviation between the mark price and the latest transaction price, with the discrepancy far exceeding normal market fluctuation ranges. My position was ultimately forcibly liquidated, resulting in a total loss of capital. The trading screenshots document the entire process, and the exaggerated price difference is astonishing. Such extreme circumstances are difficult to explain as mere market volatility; it seems more like a vulnerability in the platform's risk control mechanism or possible manipulation. Users' rights and interests are seriously harmed, and market fairness is essentially non-existent. This incident involving a leading platform should serve as a warning to the entire industry—risk control systems and price mechanism transparency are directly related to the security of every trader's funds.
