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, exchange-traded fund (ETF) and mutual fund listed on a major U.S. stock exchange and supported by Alpha Vantage. Stocks traded on non-U.S. exchanges are also supported. Indexes are not supported.
The pattern of the prices and PDI values will help you to determine if a stock is on the upside or the downside.
