Observe ETH's recent trend. The double top formed at the 3300 level has gradually evolved into a classic head and shoulders pattern. After falling from the 3300 high to around 3130, it completed a standard head-to-neckline 1:1 retracement, which also established the basic framework of the head and shoulders top.

On the technical side, 3212 is a medium-term minor resistance, while 3237 coincides with the 618 Fibonacci retracement level of this move, which warrants close attention. More importantly, 3130 not only acts as an effective support but also forms a support-resistance flip, meaning that if there is a rebound later, this level will become a resistance point.

Regarding trading directions, there are two strategies: for short positions, consider setting up a short order near 3237 with a stop at the previous high of 3307, targeting around 3167 and 3130; for bullish traders, consider placing a long order at the low of 3130 with a stop at 3060, targeting 3200 and 3237, and possibly closing the position near 3300. Overall, the support and resistance within this range are relatively clear; the key is whether the price can effectively hold above or break below these critical levels.
