$ETH Currently experiencing a wide-range fluctuation between 2900 and 3070. In terms of operation, it is recommended to buy low and sell high within this range, and to closely monitor the breakout at the edges of the range. A breakout above 3070 accompanied by increased volume can be seen as a signal that the upward trend is starting; a breakdown below 2900 with increased volume should raise caution for a return to a downward trend. Within the range, you can refer to the changes in the MACD histogram and the overbought/oversold conditions of the RSI for short-term trading.
