The pressure line of the 3420-3250 interval of Eth at a small level is very important, because the small level has a suspected head and shoulders top pattern. This interval belongs to the high point of the right shoulder. As long as it breaks through and stands firm, this pattern will not be established. If there is a needle, the long order should consider pocketing and shorting. Once the pattern is established, it will start to go down. The first low point is near the neckline position of 3280. If it falls below the neckline, it will have to fight a 3,000-point defense battle. The above is only judged based on the head and shoulders top pattern. If it is not established, the price will continue to rise. Just pay attention to the risks!
