Solana is on its own wave 5 in the 4-hour time frame
Currently, Solana is at the bottom of its short-term ascending channel and can correct up to the $38 range.
The support range of $20 can be the completion of the 5-downward wave or a part of this wave.
Solana can experience a price drop by forming the AB=CD harmonic alcove up to the support range of $20.
With the explanation that the wave BC has been able to correct 0.5 degrees of the wave AB and the length of the CD wave can correct up to 2 degrees of the BC wave that the support range of $20 overlaps with the completion of the CD wave.
