There's a good confluence with harmonics and classic TA here...
- First of all ATOMUSDT broke up and flipped S/R 23.6%
- OB on top is a perfect match with 88.6% fib - potential reversal point
If price crosses the current high (X) then this pattern should be invalid as that's where your stop-loss will be (above X) for a short setup once D is achieved.
Looks pretty solid and ATOM has history with Harmonics!
