Silver recently reversed up twice from the support area lying at the intersection of the key support level 17.50 (former powerful resistance from August), sharp upward-sloping support trendline from July and the 38.2% Fibonacci correction of the previous strong upward impulse wave from July. The upward reversal from this support area started the active wave (b)  which belongs to the short-term ABC correction 2 from the start of September. Silver is likely to extend the gains toward the next resistance level 18.50 (which reversed the price sharply earlier this month). The breakout of the resistance level 18.50 can lead to further gains toward 19.00.
