Hi I am hoping some of you very clever people could help me write a filter:
I want to plot :
1:Standard deviation channel price= close, deviations 1, fullrange, length 21
2: standard deviation channel price= close, deviations 1, fullrange,length 21
plus find stocks( any price) that are at the bottom and top channels.
I have TOS and can plot this but I cannot scan stockfetcher.
I have tried to learn but I must be missing something , ( ok Im stupid)
Thanks in advance for any help

This is kind of a do it yourself site.....some examples are in the Indacator tab, or do a search on the indacator lots of examples.
Many people will help you once you try to build a filter..even if it wont work.
Its the teach a man to fish thing........
Post up what you have tried and people will help.

eman I have tried to write it myself, but in all honesty I do not really understand it, I have been a member since inception and was happy with the technical scans already in place, I appreciate your input but would be happy if someone can help me and then I can post how I intend to use it.

I dont think they have a channel for SD
Building a custom channel indacator is litte beyond me... is this close?

Standard Deviation

Parameters Period
Avg Period
Usage Standard Deviation(10)
Normalized Standard Deviation(15)
Average Standard Deviation(10,5)
Average Normalized Standard Deviation(15,3)
Description The standard deviaition is a statistical measure indicating how much a set of data is changing over a given period of time. StockFetcher provides two different standard deviation measures (along with a simple moving average of each.) The normalized standard deviation divides the standard deviation results by the average of the closing prices as an attempt to perform some normalization to the values.

Hi Eman and Chetron, Thanks for your time and interest. I will upload a picture of the chart ( when I find out how ). Basically it has 5 parallel lines when the stock hits the extremes it gravitates back to the centreline. The technicals are beyond me but it is very accurate and I want to share it and I have no doubt you guys will turn it inside out and improve it too. Even if I cannot build a filter to show it, maybe I can build a filter to include something similar and apply the stocks to see it they fit...again many thanks

This might similar to what you describe. 21 day high/low SD channel. The long/short criteria is established when touching the new 21 day highs or lows.
