java.lang.Object org.mov.chart.graph.AbstractGraph org.mov.chart.graph.MACDGraph
public class MACDGraph
Moving Average Convergence Divergence graph. This graph draws two simple moving averages, the fast one in green, the slow one in red. When the two lines cross they indicate a Buy or Sell recommendation.
