    The Percent of Resistance (PCR) oscillator represents the resistance of a security as a percentage ratio. To calculate the ratio, PCR compares a security's closing price with its price range over a specified period of time. The PCR line oscillates on the 20 to +80 scale, where readings below 20 can be considered as a buy signal and the readings above 80 as a signal to sell.

    PCR = (Highest Highn - Today's Close) / (Highest Highn - Lowest Lown) * 100

    N – number of periods
