Chaikin Volatility Indicator
Chaikin's volatility indicator calculates the spread between the maximum and minimum prices. It judges the value of volatility basing on the amplitude between the maximum and the minimum. Unlike Average True Range, Chaikin's indicator doesn't take gaps into account.
According to Chaikin's interpretation, a growth of volume indicator in a relatively short space of time means that the prices approach their minimum (like when the securities are sold in panic), while a decrease of volatility in a longer period of time indicates that the prices are on the peak (for example, in the conditions of a mature bull market).
