In the 4-hour trend, after Bitcoin's price reached the interim high of 90,400, it closed with a long upper shadow bearish candle, initially forming a double top pattern. At this point, the upper band of the Bollinger Bands becomes a strong resistance level. After the price broke below the short-term upward trend line, the support strength of the middle band of the Bollinger Bands also became uncertain. Moreover, the price failed to break through the previous high after retesting, indicating that the technical conditions for a bearish correction have been met.
