analyzing the price action we can see a potential harmonic abcd formation with a perfect match with 1.414 extension. for me, the safest buying zone will be between 10.5 - 12.0.
I would say that the underlined area is best for investing purposes buying without leverage on 1-2 year holding period with great potential roi.
for day trading, wait for a reversal formation within the zone, and buy with 18.0 initial target and your stop below the zone.
