The top chart. Bollinger bands and an EMA .
Yellow lines are BB bands, when they widen price drops/increases. Width =fluctuation size.
Purple line is the avg and direction of the commodity.
When that purple crosses the green (green is EMA, exponential moving avg) the commodity will change direction In value as well, much like the MACD works.
