The daily line is potentially running in the 27000-31000 oscillation range. The 4h bottomed out and rebounded near the upper edge of the previous dense area at 27750. The 1h two-stage callback after 28800, backtested the upper edge of the previous dense area at 28100 to get support, and ended the callback and rushed up to 29200 again. The current position is the lower edge of the previous dense area, which belongs to the pressure zone. The probability of short-term rise is small, and the bullish trend is relatively repeated. There is no right trading signal, wait and see, attached picture:
