The small-level trend of ETH is supported by a double pattern, consisting of a head and shoulders bottom + U-shaped bottom. The current price is at the neckline position. Typically, after touching the neckline, there will be a pullback, continuously declining to form a descending wedge pattern, after which it will begin to accelerate upwards, breaking through the neckline to complete the reversal. What about going short first and then long?
