When placing an order, I clicked once and inexplicably two orders appeared. The price instantly and bizarrely dropped by $40, triggering a margin call and even resulting in negative balances. Upon verification, other platforms showed no such price at the same time—the price had severely deviated from the normal range. I wrote to request a refund, but the address could not be found. As mentioned earlier, I've added a comparison chart showing the severe deviation from normal data and other platforms' data, which ultimately led to my significant losses.
