I really don't understand this market. It goes up and down. Following the operation, buying and selling are all ceilings. Forget about the future. Wait, it's stuck at my price and can't go up. It's also the kind of high-rise that I can't react to and then falls back to a double-digit loss. Is this targeting me? I only have a 4 million plate, so they are not targeting me, right? But no matter what the operation is, it goes down immediately after closing the short and opening the long, and the same is true for closing the short and opening the long. I'm so tired.
