With 3720 as the core watershed, clarify the trend direction and operational logic:
1. Watershed positioning
3720 is the key boundary point for the effectiveness of the hourly rebound:
- Stabilizing above → Confirms the initiation of the hourly rebound, with the trend biased upwards;
- Not stabilizing above → Insufficient rebound strength, the downward trend continues.
2. Below the watershed (downward trend)
If it does not stabilize above 3720, the downward trend continues, with support points below as references for short-term buying on dips:
- Key support levels: 3655, 3612, 3570, consider placing long positions with light positions around these levels.
3. Above the watershed (rebound trend)
If it stabilizes above 3720, the rebound trend is confirmed, with resistance points above as references for short-term selling on rallies:
- Key resistance levels: 3755, 3800, 3844, consider attempting short positions with light positions around these levels.
Summary
3720 serves as the watershed to determine the trend direction, with support/resistance points corresponding to different operational nodes in various phases of the trend. Actual trading needs to combine real-time trading volume and candlestick patterns to verify signals, strictly set take-profit and stop-loss levels, and control risks.$ETH #以太坊走势
