The Chaikin's Volatility indicator was invented by Mark Chaikin, a longtime stock trader and analyst. The indicator is used to measure volatility by analyzing the gap between the minimum and maximum price of an asset over a certain number of periods. According to the theory, the indicator can be used to recognize market phases. New tops/bottoms on the chart and an increase in volatility in a short time indicate panic buy/sell. If the market tops/bottoms are accompanied by a decrease in volatility for a long time, this indicates a stable bull/bear market. It is also worth noting that an uptrend/downtrend reversal may be accompanied by a slow or short-term increase in volatility.
