At the 4-hour chart level, the K-line body continues to oscillate within a narrow range between the middle and upper bands of the Bollinger Bands, with the Bollinger Bands channel showing a horizontal extension. The distance between the upper and lower bands is narrowing, and the RSI indicator hovers around 62. Although it has not entered the overbought area, it is close to the warning line. Combined with the suppressive effect of the upper band of the Bollinger Bands, the price indeed faces significant resistance to the upside. The current price is closely adhering to the upper band of the Bollinger Bands, with small pullbacks occurring each time it touches the upper band, but the low points of the pullbacks are gradually rising, forming the early shape of an ascending triangle. This technical formation indicates that although there is significant pressure above, market buying support remains solid. In the morning, one can expect a wave of pullbacks.
