Last week GLD dropped into the Green Target box and then turned up strongly:

Looking at 30 min chart we can see that bears could have pushed lower one more time but bulls manage to push GLD over the critical resistance and by doing that they confirmed completion of a corrective structure.
It is possible to count the large A-B-C down corrective structure in Gold that took two years completed.
Bulls have a setup to start a new strong and large impulsive rally targeting new all time highs.
