The platform Upway, on April 20, at 7.43 points, liquidated my long-short lock order at the non-existent market price. It had been open for more than an hour, and their spread was 20. Their customer service explained that the investigation was expanded to 354 points at this time. This was simply a serious manipulation of prices and spreads. Which platform has such a big spread, and it has been open for nearly two hours. On April 20, 07:43:17, 4 of my orders were liquidated, two long orders were liquidated at 4759.32, 4765.14, and short orders were liquidated at 4768.68, 4768.65. Moreover, the highest point of the K-line market at 7.43 at this time was only 4765.57, which was not at all the price of 4768.65. This is simply a scam. Very unfair. This resulted in me losing money, and this was one of them. I suffered unfair treatment many times, with a total loss of 4,300 US dollars. I need Upway to compensate me for my principal of 4,300 US dollars.
