Mobile operation went wrong, clicking sell twice with no response, and as a result, the chips were directly cleared by accident. After the market opened, I found a more promising asset on the internal market, and the name was also good, but then I thought about it—such a situation usually indicates that liquidity will be dispersed, and institutions might have already been signaling an exit. So I decided to withdraw altogether; rather than betting on the subsequent trend, it's better to cut losses in time and look for the next opportunity. Mobile trading indeed easily leads to such accidents; the double-click confirmation issue is quite annoying.
