Advance-Decl Ratio (Indicator)Analysis Techniques & Strategies
Advance-Decl Ratio (Indicator)
| Name | Expression | Default | Description |
| AdvIssues | Numeric | Close of Data1 | Price data considered as Advancing Issues. |
| DecIssues | Numeric | Close of Data2 | Price data considered as Declining Issues. |
The Advance-Decl Ratio indicator calculates the ratio of advancing issues to declining issues and plots this value. The relationship between advancing issues and declining issues is known as market breadth. 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 Ratio accurately, the chart must contain both the Advancing Issues and the Declining Issues and the inputs must specify the correct data number for each.
| Plot Number | Plot Name | Default Color | Description |
| Plot1 | A/DRatio | Cyan | Plots the Advance Decline Ratio value. |
| Plot2 | BaseLine | Green | Plots a zero line for reference. |
When applied to a chart, this indicator displays one plot in a separate subgraph from the price data.
In order to apply the Advance-Decl Ratio indicator to a chart, you must plot two symbols. Data1 represents the number of advancing issues and their volume. Data2 represents the number of declining issues and their volume. Historically, Advance-Decl Ratio is applied to the NYSE Advancing issues (Data1) and NYSE Declining Issues (Data2).
