About Advance/Decline Technical Analysis.

Advance/Decline-based indicators have become one of the most important tools in the analysis of the indexes, exchanges and the entire stock market. Historically the advance/decline technical analysis was applied to the NYSE (New York Stock Exchange). Nowadays, it is widely used with other indexes to determine the breadth of the different market sectors.

Advance/Decline technical indicators are based on the following data:

• Advancing Issues (stocks) - number of stocks that are traded above the previous day's closing price.
• Declining Issues (stocks) - number of stocks that are traded below the previous day's closing price.
• Advance Volume - summary volume of the advancing stocks.
• Decline Volume - summary volume of the declining stocks.

In the quotes table above, we collected the most popular quotes of the advance/decline-based technical indicators, such as Advance/Decline Ratio, Advance/Decline Percentage Oscillator, TRIN, etc.

The formula of the Advance/Decline Ratio is:

A/D Issues Ratio  = (Advancing Issues) / (Declining Issues)

The formula for calculation of the Advance/Decline Percentage Oscillator is

A/D Issues PO = [(Advancing Issues) - (Declining Issues)] / [(Advancing Issues) + (Declining Issues)]

Similar formulas are used to calculate AD volume indicators:

A/D Volume Ratio  = (Advancing Volume) / (Declining Volume)

A/D Volume PO = [(Advancing Volume) - (Declining Volume)] / [(Advancing Volume) + (Declining Volume)]

TRIN is calculated as the ratio of Advance/Decline issues to volume ratios:

TRIN = (A/D Issues Ratio) / (A/D Volume Ratio)
