Inverse fisher Rvi from Mladen:::::

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:

RVI = Close - Open
High - Low




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.
