Inverse Fisher RVI:
Relative Vigor Index indicator used in technical analysis to
measure the conviction of a recent price action and the likelihood that
it will continue. The RVI compares the positioning of a security's closing price relative to its price range, and the result is smoothed by calculating an exponential moving average of the values.
The indicator is calculated by using the following formula:
This indicator has an addition of inverse Fisher Transform to the RVI.
The Inverse Fisher Transform normalizes the values in the desired
range (-1 to +1 in this case) which helps in assessing the overbought
and oversold market conditions.
