I was originally planning to ask Lao Wu why I didn't have it, but seeing only this little profit, I felt a sense of balance in my heart. Today, SPK did perform well, but brushing Alpha was a bit like walking on thin ice. Everyone is good at brushing liquidity, but this can easily lead to collapse, and the wear and tear of poor liquidity is relatively large. Tomorrow, I may give up high liquidity, even if the wear and tear is slightly larger, it is stronger than being ambushed.
