When I woke up, I found that the market always moves in unexpected ways. You think it will fall, but it has actually hit the bottom. You think it will rise, but it has actually reached the top. The change happens in an instant. Last night, the US stock market opened low and rebounded to stabilize the situation. This morning, the Japanese economy rebounded to stabilize the sentiment. Yesterday, I saw many people panicking. In fact, it was killing contracts. So brothers, if you want to survive in this market for a long time, the first thing is not to play contracts. I have never seen anyone get rich by contracts.
