Yesterday, the Asian and European sessions maintained a range of fluctuations until the release of the US CPI data. The market rushed from 2311 to 2341, an increase of 30 US dollars. Then it adjusted back to 2320 and quickly hit 2340. It fell back at the end of the session, indicating that there was great pressure from above. The lowest test in the morning was 2317. Compared with yesterday's US session, the volatility was huge. There is a risk of being carried away if you are not careful. With the support of the initial jobless claims data tonight, the first wave will look at the 2320 line, and the second is the 2328-30 line. This position is also an opportunity for short selling.
