A/D Line

The A/D Line is the most widely used indicator measuring market breadth. It represents a cumulative total of the number of stocks advancing vs. the number of stocks declining. When the A/D Line rises, it means that more stocks are rising than declining (and vice versa).

BigCharts calculates the AD Line for all markets and automatically selects the appropriate market indicator for your focus security. For example, if you are analyzing a chart on IBM which trades on the NYSE, and you choose the A/D Line, the system will automatically apply the A/D Line for the NYSE.
