Chaikin Volatility (10)Volatility

Timeframe M1 · unit %

What it measures

The percentage change in a 10-bar EMA of daily high-minus-low range over the past 10 bars. Captures the rate of change of the bar range expansion or contraction.

How Janira reads it (bullish vs bearish)

Positive values indicate bar ranges have been expanding relative to 10 bars ago - volatility is growing. Negative values mean ranges have been contracting. Zero is the neutral baseline. This indicator measures the VELOCITY of volatility change, not its absolute level.

In plain language

Rather than asking 'are bars wide or narrow?', Chaikin Volatility asks 'are bars getting wider or narrower compared to 10 bars ago?' It's a derivative of volatility - the acceleration gauge.
