StockCharts Breadth Data


StockCharts provides detailed breadth data for the AMEX, CDNX, Nasdaq, NYSE and TSE. Chartists can create indicators using advances, declines, advancing volume, declining volume, new 52-week highs and new 52-week lows. There are also indicators for net advances (advances less declines), net advancing volume (advancing volume less declining volume) and net new highs (new highs less new lows). These indicators can be used to create the AD Line, the AD Volume Line and the Net New Highs indicator.

Data Characteristics

Breadth data for the major stock exchanges is calculated in-house at StockCharts using a three-step process. First, StockCharts maintains component lists of all stocks traded on these exchanges. Second, our scan-engine uses these component lists to run scans based on the price data for the individual stocks. Third, the data is updated and published to our website.

Data from StockCharts may differ from other sources due to differences in the index components and price data. Index components change and require updates on a regular basis. Also note that StockCharts uses dividend-adjusted data for its calculations, while other sources, such as Dow Jones and the Wall Street Journal, use non-adjusted data.

Chart Example

The chart example below shows the Nasdaq AD Line ($NAUD) in the main window and the raw data in the indicator window. The AD Line is a cumulative measure of net advances (advances less declines). The indicator window shows the daily changes in net advances ($NAUD). Notice how it moves above/below the zero line as net advances shift from positive to negative. The window below shows the 20-day SMA of Nasdaq Net Advancing Volume ($NAUD), which acts as an oscillator.
