In the 4-hour chart, the Bollinger Bands are still trending downwards, and the upper band is also clearly pressing down, overlapping with the EMA80. There may be a continued break down towards the EMA60 position during the day. The current candlestick is once again encountering resistance from the middle band. The MACD is shrinking below the 0 axis, and the fast and slow lines are converging for the first time. Attention can be paid to the position approaching the 0 axis to consider opening a short position.
