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.
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 ===
Yellow: don't care
I think it can be useful!
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.
