From the current market situation, the four-hour chart shows the price staying close to the lower band of the Bollinger Bands, with obvious insufficient bullish momentum and a gradual dominance of the bears. On the one-hour chart, although there is alternating bullish and bearish movement and the MACD is gradually forming a cross, there are no clear signs of a reversal in the short term. The probability of a pullback is relatively high, so afternoon trading should mainly focus on shorting from the highs.
