Ethereum (ETH) has performed poorly recently, failing to maintain its intraday rise. From the 4-hour and 12-hour time frames, market sentiment still appears weak. Investors may need to exercise caution and wait for clearer buy signals to emerge, or take advantage of rebounds to sell at higher prices.

From the 12-hour chart, ETH is currently in a range-bound oscillation but leans towards bearish. The price is below the weekly pivot of $4475.70 and EMA9, close to but still above the support level of $4163.40. There are currently no clear signals to go long.

The 4-hour chart shows that ETH is exhibiting a medium intensity downtrend. The closing price is below the EMA9/21 moving averages and the weekly pivot, with the volume-weighted average price (VWAP) trending downward. If considering a short position, the stop loss could be set at $4300 (based on the 4-hour close). Potential profit targets could be set at $4220, $4163.40, $4120, and $4050. If the price breaks below $4163.40 (based on the 4-hour close), it may trigger further declines.

From the 1-hour chart, ETH is hovering around the daily pivot of $4268.05, and the VWAP remains stable. There are no clear trading signals in this timeframe.

The comprehensive strategy recommendations are as follows:
1. 4-hour level: Short on the highs within the range of $4268-$4300; if it breaks below $4163.40, it may open up downward space towards $4120/$4050; if it breaks above $4300, reassessment is needed.
2. 12-hour level: Maintain a cautious attitude below $4475.70.
3. 1-hour level: Wait for the price to close above the pivot point and for the VWAP to rise before considering going long.

The market is still in an uncertain state, and investors should closely monitor key price level breakthroughs and adjust their strategies in a timely manner according to market changes. At the same time, it is recommended to combine other technical indicators and fundamental factors to make more comprehensive investment decisions.
