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.
Introduction
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 hurt)...
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.
=== Bar Color Meaning ===
Green: uptrend
Yellow: don't care
Red: downtrend
I think it can be useful!
Thanks!
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)...
Phase Change Index script.
This indicator was developed and described by M. H. Pee (Stocks & Commodities V.22:5 (28-37): Phase Change Index).
Other indicators of M. H. Pee:
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.
Ehlers Fisherized Deviation-Scaled Oscillator script.
This indicator was originally developed by John F. Ehlers (Stocks & Commodities V. 36:11: Probability - Probably A Good Thing To Know).
Ehlers Deviation-Scaled Moving Average indicator script.
This indicator was originally developed by John F. Ehlers (Stocks & Commodities V. 36:8: The Deviation-Scaled Moving Average).

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...
Here is a nice little script that highlights areas of volume using standard deviation, you can choose the look back periods.
This script is based on the excellent script by: @SteynTrade -
I have simplified it a bit and made it readable to my taste using alpha to highlight high volume areas.
Enjoy.
Moving average deviation rate
Simple moving average deviation rate and standard deviation.
The bollinger band is momentum value standard devition.
Bat the bollinger band is not normal distribution to close price.
Moving average deviation rate is normal distribution.
This indicator is draw Moving average deviation rate and fill area 2σ standard devition.
