More importantly...the 200 MA on the 4 hour. Been rejected twice before...sitting right at it now. That would also cause a pop up to that line on your chart quickly IMO.
Also, the bottomless pocket gang may be running out of funds. They are trying to hold GDX back...but for the first time in MONTHS the volume is huge and they are getting steamrolled every time they throw up their huge ASK sizes. WAY early, but this 'could' be something.
EDIT: Perfect stop at the middle bolly on the hourly in period 1. Maybe they are still in full control. LOL
