Relative Vigor Index (RVI) Indicator

Relative Vigor Index

The Relative Vigor Index measures the strength of a trend. It does this by comparing the closing price of an instrument to its trading range. Traders will look at whether the price of an instrument at closing was higher or lower than its opening price.
