Advance-Decline indicators can be divided into two groups: issue-based indicators, which count the number of advancing issues, declining issues and unchanged issues on a given exchange, and volume-based indicators, which total the volume of advancing issues, the volume of declining issues and the volume of unchanged issues. Issues are mostly common stocks, but can also include closed-end funds, ADRs and preferred stocks.

This group of advance-decline indicators covers five major exchanges. The AMEX, Nasdaq and NYSE are covered on the US side. The Canadian Venture Exchange (CDNX) and Toronto Stock Exchange (TSE) are covered on the Canadian side. The Canadian indicators are updated after the market close (end-of-day EOD).
The advance-decline data for the five exchanges is sourced from Interactive Data Corp (IDC), StockCharts's primary data feed provider. This data is received in tick form, which StockCharts then converts into intraday and daily data for use in charts.
Note that StockCharts also calculates and publishes a series of breadth indicators specific to the major index ETFs and sector SPDRs. These include Advance-Decline Percent, Advance-Decline Volume Percent and High-Low Percent. These “in-house” breadth indicators are updated after the market close (end-of-day EOD).
Net Advances and Net Advancing Volume are also featured in this indicator group, such as AMEX Advance-Decline Issues ($AMAD) and NYSE Advance-Decline Volume ($NYUD). Net Advances equals advances less declines. Net Advancing Volume equals the volume of advancing issues less the volume of declining issues. These “net” versions can be used to create other indicators, such as the AD Line and AD Volume Line.
The first chart shows the Nasdaq AD Line ($NAAD) using intraday data (30-minute). Chartists can create the AD Line by selecting “cumulative” as “Type” under “Chart Attributes”. This short-term picture can be used by day and swing traders. Click here for a live version of this chart.
The second chart shows the NYSE AD Line ($NYAD) using daily data, while the indicator windows show NY Advances ($NYADV) and NY Declines ($NYDEC) for reference.Click here for a live version of this chart.
StockCharts users can find these symbols using two different searches: one for advance-decline issues and one for advance-decline volume. These lists will also show the starting date for each data series. The example below shows a sample list of symbols.
Notice that users can search for breadth indicators by quantifying their search criteria using the advanced search functions. Searching for “issues -percent” is enough to highlight the advance-decline issues indicators. The terms preceded by a minus sign (-) are excluded to narrow the search and remove unwanted names.
