Relative Volatility Index (RVI)

Description

The Relative Volatility Index (RVI) has many similarities to the RSI indicator. Donald Dorsey developed the RVI, which uses the standard deviation instead of the daily price span. To determine the underlying volatility of the instrument, the RVI uses the standard deviation over a period of 10. The RSI indicator is then used on the results, which normalizes them. What comes from this is displayed on a scale of 1 to 100.

Interpretation

Values above 50 assume an increase in volatility. Values below 50 imply a drop in volatility. Dorsey recommends using the indicator as a filter for other indicators.
