Its just a straight forward consequence from Fourier's sampling
theorem, which I (unfortunately) have not invented.
I stumbled across it, when I tried to find the reasons for some
differences between the results from my trading system and my "real
world" results. This NT stuff may give a measure, what we can get out
from a given data stream, even if we would use the "best" trading
system possible.
Like I wrote in my first posting, usage of stadev (and mean||) is only
a quick & dirty approach of using probability distributions for wins /
losses and a p2w/lmtxx% (probability-to-loose/win-more-than-xx%)
cluster, which is what I do.
