Oscillator Historical Volatility Ratio is a volatility indicator based on the "yesterday" / "today" price ratio
It has four configurable parameters:
- First deviation period - first standard deviation calculation period
- Second deviation period - second standard deviation calculation period
- Applied price - calculation price
- Threshold - "low" volatility threshold
Calculation:
HVR = StdDev1 / StdDev2
where:
StdDev1(ST) - standard deviation with the First deviation period
StdDev2(ST) - standard deviation with the Second deviation period
ST = LOG(Price/PrevPrice)
