I won't attempt to explain what a standard deviation is but I will say that
I think it is important for a trader to have an understanding of basic
statistics. That doesn't mean you should use it but you should understand
the principles.
Two good books available at most libraries are 'How to Think About
Statistics' by John Phillip and 'Statistics Without Tears' by Derek
Rowntree.

Subject: standard deviations
Hey RTīs,
Peter was asking if 2 instead of three standard deviations wouldnīt be
enough.
Could you please let me know, what a sd is?
Thanks - Ulrich
