May Silver’s last thrust exceeded an 18.585 target by two cents, implying that there are more buyers out there waiting to be satisfied. Assuming the  pullback begun from Monday’s high is prelude to a follow-through rally, the rally would need to clear January’s 18.900 high to fully re-energize the bull trend.  It could begin from any retracement low north of 17.335 and would be announced by a booster stage thrust of at least 55 cents.
