Description

• This indicator has been developed by Donald Dorsey
• RVI is a revised version of RVI original in which input is closing price, where RVI uses high and low price
• Incase of RVI, it uses standard deviation (SD) as input instead of close price
• As it uses standard deviation, it helps to understand the direction of price movement in which volatility stands

Interpretation

• If RVI is above 60, it indicates that volatility is in favour of upward price movement
• If RVI is below 40, it indicates that volatility is in favour of downward price movement
• RVI being a volatility indicator will give good trading signals when used along with other oscillator like RSI, stochastic etc, as they consider price as basic input to give price trend & reversal signal

Returns/Output

RVI values of stock for the specified period.

Formula

RVI = [RVI(high) + RVI(low)] / 2
RVI (input) = 100 - (100 / (1 + RV(input)))
Where,
RV =(Avg_of_n_updays_standard deviation)/(Avg_of_n_downdays_standard deviation) Up days = when high > Pvs high & for low > Pvs Low Down days = when high < Pvs high & for low < Pvs Low
