Chaikin Volatility

Marc Chaikin measures volatility as the trading range between high and low for each period. This does not take trading gaps into account as Average True Range does.

Chaikin Volatility should be used in conjunction with a moving average system or price envelopes.

Trading Signals

Look for sharp increases in volatility prior to market tops and bottoms, followed by low volatility as the market loses interest.

    The breakout from the range is not accompanied by a significant rise in volatility.
  3. Volatility starts to rise as price rises above the recent high.
  4. A sharp rise in volatility occurs prior to a new market peak.
  5. The sharp decline in volatility signals that the market has lost impetus and a reversal is likely.


See Indicator Panel for directions on how to set up Chaikin Volatility. The default settings are:

  • H-L period of 10 days
  • Volatility smoothing - 10 days

To alter the default settings - see Edit Indicator Settings.


To calculate Chaikin Volatility:

First, calculate an exponential moving average (normally 10 days) of the difference between High and Low for each period:

                      EMA [H-L]

Next, calculate the percentage change in the moving average over a further period (normally 10 days):

                      ( EMA [H-L] - EMA [H-L 10 days ago] ) / EMA [ H-L 10 days ago] * 100
