        Article summary

        Relative Volatility Index (RVI) is a volatility indicator based on Relative Strength Index (RSI). RVI uses 9-period standard deviation over several last bars instead of average price change, which is used in RSI. The indicator values utilize on the scale from 0 to +100 with overbought/oversold levels. The volatility direction is interpreted as upside when the line is above 50, and downside when the line is below 50.

        RVI = (RVIorig of highs + RVIorig of lows) / 2
        RVIorig = 100 * (14-days EMA of U) / (14-days EMA of SD)
        U = SD, if current price is above the price of previous period
        U = 0, if the current price is below the price of previous period 

        where:
        EMA – Exponential Moving Average
        SD – 10-days' standard deviation
        RVIorig of lows – Relative Volatility Index for minimums
        RVIorig of highs – Relative Volatility Index for maximums
