This wave of short positions was the most basic mistake; there were signs of a decline here, so I placed an order and went to do something else. Later, it dropped directly, and I forgot to cancel the order. I just realized a turning point had appeared, and I was about to place a long position and go to sleep when I found out the short position was already trapped (originally at 2:12, I was going to place a high-level short, then at 2:15, noticing signs of a decline, I changed it to 2192, and my phone screen was off while I kept an eye on the computer).😭😭😭😭
