The Advance Decline Line is used as a measure of market breadth. The Advance Decline Line is a cumulative total of the difference between advancing issues and declining issues and has been proven as an effective measure of the stock market's strength.

For example, if a stock market index is rallying but there are more issues declining than advancing, then the rally is narrow and much of the stock market is not participating. To plot the Advance-Decline Line accurately, the chart must contain both the Advancing Issues and the Declining Issues and the inputs must specify the correct data number for each.
