DEFINITION of 'Relative Vigor Index  RVI'
An indicator used in technical analysis that measures the conviction of a recent price action and the likelihood that it will continue.

The indicator is calculated by using the following formula:
BREAKING DOWN 'Relative Vigor Index  RVI'
The RVI indicator is calculated in a similar fashion to the stochastic oscillator, but the vigor index compares the close relative to the open rather than to the low. Traders expect the RVI value to grow as the bullish trend gains momentum because in this type of environment, a security's closing price tends to be at the top of the range while the open is near the low of the day.
