Price Direction Indicator (PDI) Calculator and Chart Maker

Savvy investors know that buying stocks on the upside is the way to make money. For lengthy upsides of several months to many years, the total return can be large. Conversely, for an extended downside price series, most investors and traders lose money because most of the possible trades are unprofitable.

Use the Price Direction Indicator (PDI) to analyze if a price pattern has peaked or bottomed for any stock listed on a major U.S. stock exchange and supported by Quandl.

The pattern of the prices and PDI values will help you to determine if a stock is on the upside or the downside.
