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 spectacular. That's why people buy stocks. 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 U.S. stock exchange and supported by Quandl.

On the form below, simply enter a symbol plus the selected dates for the analysis and price series interval. Then click on the Calculate PDI button, and in a few seconds the price and PDI chart will be displayed on a new page. The pattern of the prices and PDI values will help you to determine if a stock is on the upside or the downside.
