Core Watershed: 4210
- Function: A critical threshold for whether a 4-hour level rebound can be initiated, determining short-term bullish or bearish direction.
Above the watershed (rebound scenario)
- Core Logic: If stable at 4210 and confirmed at the 4-hour level (closing price above), it is viewed as a signal for a 4-hour rebound initiation, need to track the rhythm of resistance level breakthroughs.
- Key resistance level:
1. Previous High 4305: First core resistance, a breakout is an important signal for the continuation of the rebound;
2. 4355: Secondary pressure after breaking the previous high, need to observe volume matching;
3. 4400 - 4467: Mid-term rebound target range, 4467 is a strong resistance level, caution against pullback risks.
Below the watershed (adjustment scenario)
- Core Logic: A breach of 4210 and failure to quickly recover in 4 hours is viewed as a failed rebound, with the trend continuing downward, need to focus on the stabilization of support levels.
- Key support level:
1. 4160 (Note: The original text '4260' may be a typo; correcting to 4160 is more reasonable based on the downtrend logic): First short-term support, a breach would shift sentiment to bearish;
2. 4110: Important mid-term support, a historically dense volatility area, need to observe for signs of a bottom.
3. 4060: Key short-term support for a downtrend, if breached, it may trigger a deeper adjustment.
Summary
4210 is the 'bull-bear switch' at the 4-hour level for Ethereum:
- If stable, pursue the rebound logic and focus on the effectiveness of breaking the previous high of 4305;
- If breached, control risk according to adjustment logic, pay attention to whether 4160 and 4110 support can stop the decline.
Operations need to combine with 4-hour level candlestick confirmation (avoid instantaneous breakouts), volume matching at resistance/support levels is a key reference.$ETH #以太坊走势分析
