Silver: The 4H chart's Bollinger Bands appear to be tightening on this commodity as prices prepare for a volatile jump. With bearish crosses on the hourly and daily Slow Stochastic, as well as an over-bought indication on the 4-hour RSI, the next major movement may indeed be in a downward direction. Forex traders involved in commodity trading can take advantage of this knowledge by going short on Silver and riding out what appears to be building up to be a sharp movement in price.
