Solana could drop to support

From the 7.5 back in December last year to the 32 high in mid-July, Solana has has a very good run with a gain of more than 400%.
However, after this recent high, the coin started to roll back down and now is trading at 21.32.
I believe more losses will come and we can see a test of 15 zone support.
I'm looking to sell rallies with negation above 27
