The daily line is potentially running in the 27000-31000 oscillation range. The 4h is at the lower edge of the oscillation zone. It made a successful bottoming signal last night, but it did not stand firm and returned to around 27000 again. The lower edge of the daily oscillation zone, the 1h focuses on the pressure of 28300 and the support of 27000. The current market cannot see a breakthrough up or down. There is no trading opportunity I want, so just wait. Attached picture:
