Silver seems to be in the final E leg of that 4th wave triangle pattern (ABCDE). I take the surge we saw this Friday to be a B inside an ABC correction. The final C leg can go as low as $18,50, but I do not think it will go that low.
Note that the orange in the chart constitutes the highest scale, followed by white and green.
Settling above the $20 mark is a strong sign that the correction is likely over and I would assume it to be a signal that the bull is alive and well.
