Is this a market for people to play with? Fortunately, I followed my own rules and did not enter the US stock market today, otherwise I would have to shut myself down. This kind of market is a back and forth for a high-multiple short-term player like me. At present, this kind of market is either a short position near 2690 or a long position near 2550. It is torture to enter this oscillating area in the middle. I made money today and my mentality is better. I read novels and drank milk tea and watched Da Bing and Er Bing play tricks on people here.
