BHP - Bouncing off from key support after Head and Shoulder

BHP formed Head and should pattern and broke the neck line on Aug 18. The stock has exactly fallen down $13.23 (measured distance from head to neck line) , which is right now bouncing off of the support line 52.45. I expect this stock to chop side ways for some more time hitting short term target 58.18, 59.82 and eventually break out to fill gaps at 64.48 and 70.52

Trade closed: target reached:

Short term target hit 59.82
