Chaikin Volatility (CHV)
- DarkLight
The Chaikin Volatility (CHV) study is a technical indicator that measures volatility by comparing the spread between security's High and Low prices over a period (not including gaps in price movements). CHV is calculated as the difference between two EMAs of a volume-weighted Accumulation/Distribution (A/D) line.
CHV = (EMAn [H-L] - EMAi [H-L]) / EMAi [H-L] * 100
where:
EMAn [H-L] – the Exponential Moving Average of High and Low prices for n-period (Length)
EMAi [H-L] – the Exponential Moving Average of High and Low prices for i-period (ShiftLength)
INPUTS
Input | Description |
---|---|
Length | The number of periods the study uses to calculate the EMA |
ShiftLength | The number of periods the study uses to calculate the EMA a few periods ago |
