Hi,

I tried searching for the RVI Indicator but couldn't find.

Can you please share the pcf for this indicator. More on the formula in the below link

The formula as presented in the link would seem to be the following (using a sum or simple moving average).

`100 * SUM(IIF(STDDEV10 > STDDEV10.1, STDDEV10 - STDDEV10.1, 0), 24) / SUM(ABS(STDDEV10 - STDDEV10.1), 24)`

Where `10` is the standard deviation period.
Where `24` is the smoothing period.

But other sources would seem to use Wilder's smoothing for this instead.

`100 * XAVG(IIF(STDDEV10 > STDDEV10.1, STDDEV10 - STDDEV10.1, 0), 27) / XAVG(ABS(STDDEV10 - STDDEV10.1), 27)`

Where `10` is the standard deviation period.
Where 14 is the smoothing period and `27` is the ((2 * smoothing period) - 1).
