Silver traded lower last Thursday before recovering. Recent weakness has resulted in a break of a trendline drawn from the Oct 5 low. This highlights a bearish threat and exposes key support at $22.510, Dec 13 low. This level was pierced last week, a clear break of it would open $21.883, Nov 13 low. Key short-term resistance is $24.606, Dec 22 high. A move above this level would reinstate a bullish theme.
