I opened an order on the platform around 2:15 Beijing time on June 18, 2026. My account had over 7,000 cents in margin. Without any operation on my computer, it automatically closed my position, and the margin was sufficient. I reported to official customer service, but they said I operated it myself. If I had caused a margin call myself, I wouldn't have contacted you. This caused me a loss of $120. Please investigate thoroughly: a total of 6 orders.
