This adds volatility bands to the Variable Index Dynamic Average (VIDYA). The bands are calculated using the exponential moving average of the standard deviation of the VIDYA.
Thanks to everget for programming the VIDYA for tradingview.
The standard deviation measure the dispersion of a data set, in short this metric will tell you if your data is on average closer or farther away from the mean. Its one of the most important tools in statistics and living without it is pretty much impossible, without it you can forget about Bollinger-bands, CCI, and even the LSMA (ouch this...
This indicator shows price in relation to the standard deviations in a normalised way.
It can be seen as a kind of Bollinger Bands, where the bands stay the same size apart and price amplitude is modified between them,
or as a 'normalised' version of my BBC indicator.
Contrary to the popular use where price is seen as BOUNCING AGAINST the different deviations...
An idea I had today morning so I had to write. It seems to detect trends well. It has three phases like a semaphor, painting the chart bars of green, yellow or red.

Yellow: don't care
I think it can be useful!
Hello traders and developers!
I was wondering how built-in "dev" function in Pine is calculated so I made a little research.
I examined 7 samples:
0) "dev" function itself
1) "dev" according to its description: series - sma(series)
2) Mean Absolute Deviation
3) ratio of the absolute difference from 1) divided by period
4) ratio of the difference from 1)...
Hampel Filter script.
This indicator was originally developed by Frank Rudolf Hampel (Journal of the American Statistical Association, 69, 382–393, 1974: The influence curve and its role in robust estimation).
The Hampel filter is a simple but effective filter to find outliers and to remove them from data. It performs better than a median filter.

Corrected Relative Volatility Index. This indicator was originally developed by Donald Dorsey (Stocks & Commodities V.11:6 (253-256): The Relative Volatility Index).
The indicator was revised by Dorsey in 1995 (Stocks & Commodities V.13:09 (388-391): Refining the Relative Volatility Index).
I suggest the refined RVI with optional settings. If you disabled...
