Charts to watch

I am becoming interested in the metal markets. The Copper, Silver and Gold charts are displaying possible Head & Shoulders bottom patterns. Although the left shoulder is awkward. However, a decisive close below this week's lows would alter the above analysis and could lead to a retest of the June lows. But my guess is the right shoulder which will be subject to considerable change before the next trend is declared. I would buy an upside breakout but would not short below the september lows.
