Average True Range Percent (ATRP)


Average True Range Percent (ATRP) expresses the Average True Range (ATR) indicator as a percentage of a bar’s closing price.

How this indicator works

  • ATRP is used to measure volatility just as the Average True Range (ATR) indicator is. ATRP allows securities to be compared, where ATR does not.
  • ATR measures volatility at an absolute level, meaning lower priced stock will have lower ATR values than higher price stocks. ATRP displays the indicator as a percentage, to allow for securities trading at different prices per share to be compared.


ATRP = (Average True Range / Close) * 100
