The analysis of $ETH on the 4-hour chart shows that the candlestick body is continuously oscillating in a narrow range between the middle and upper bands of the Bollinger Bands. The Bollinger Band channel is exhibiting a horizontal extension, with the distance between the upper and lower bands narrowing. The RSI indicator is hovering around 62; although it has not entered the overbought zone, it is approaching the warning line. Combined with the resistance effect of the upper Bollinger Band, the price indeed faces significant resistance in its upward movement. The current price is closely touching the upper Bollinger Band, and each time it reaches the upper band, there is a slight pullback. However, the low points of the pullbacks are gradually rising, forming a preliminary ascending triangle. This technical formation indicates that, despite significant pressure from above, market buying support remains robust, and a pullback can be anticipated in the morning.
