I understand WHAT standard deviation is, but I don't what I'm looking when I see it on the Column's screen. If I see, for example, .20, what is the story that it is telling me?
Thanks in advance,
Dean

This explanation might help http://www.tradeideas.com/Glossary/Standard_Deviation.html (http://www.tradeideas.com/Glossary/Standard_Deviation.html). In terms of your column value of .20  i believe this refers to 1/5 of a standard deviation but without a picture/snapshot of your screen, it's hard to be definitive.
Yep, below is right. It is 20 cents

No it means the standard deviation is 20 cents

Id like to create charts of my variables that include the average and the standard deviation of each series. SO the first variable x1 would be plotted against the average of x1 and the average of x1 plus and minus the standard deviation. Now in order to do this I believe I have to create a scalar for each and then generate a new series of that one variable repeated. I have many variables with different naming conventions. My question, is there a simple way to program the creation of these scalars and series? Thanks

Hi,
$.0.20 in the column can be best described as the average distance between the each price in the list and the middle of the list which is $0.20 in this case.
Your question would best be answered by one of our Traders. Please write to: info@tradeideas.com and we can have one of them speak with you.
Thanks.
