This indicator, created in the early 1960's, uses an adjusted advance deline line as its basis. Subtract the declines from the advances and divide that difference by the total issues traded. Then calculate a cumulative total as you would with the advance decline line. Originally developed as a weekly indicator, the Coppock Breadth Indicator can also be adapted to daily breadth data.

Data components required:

- Advances - Declines - Total Issues

What Does Market Breadth Mean? A technique used in technical analysis that attempts to gauge the direction of the overall market by analyzing the number of companies advancing relative to the number declining. Positive market breadth occurs when more companies are moving higher than are moving lower, and it is used to suggest that the bulls are in control of the momentum. Conversely, a disproportional number of declining securities is used to confirm bearish momentum.

The market, in which a security is traded, has to be selected from the parameter drop-down menu (single klick on the index name, then the drop-down appears); e.g. if the Coppock Breadth of "Adidas" should be calculated, one has to select "DAX".
