[GDX] update

The backlink model had to be updated slightly but the concern is the same, this could be WC4 and now having trouble breaking out of a DDT at the blue arrow.  Stops should be at the red arrow for now.  I am hoping that this eventually breaks down to a lower low than W3 below.  That would be the exact fulfillment of Avi's long standing model and it would remove the more bearish long term EWI model.  Avi and EWI models should be diverging right now.  We should know within a couple days.
