The Chaikin Volatility Indicator is one of a few indicators that are designed to try and measure price movement fluctuations. Chaikin takes the daily price range (daily high minus daily low) as the fundamental measure of volatility. With this indicator, a widening range is, by implication, associated with higher volatility.
The indicator oscillates around the zero lines and fluctuates between a scale of +100 to -100. It can be used on a daily chart as well as on a weekly or monthly chart. All values above the zero line represent rising volatility, and the gradient of the rise implies the seriousness of potential floors forming. The Chaikin Volatility is not specifically used to define exact signals but is considered as more of an assisting tool in the trading system.
