I believe it has always been feasible, Lionel.
A 'forward shift' [horizontal shift n] plots the n-day-ago ma -- most
modern TA packages plot the extended ma beyond the last bar.
A 'backward shift' [horizontal shift -n, used mostly for cycle analysis]
plots today's ma n-days back.

Glen:
The original formula says to offset ahead (into the future). Though I
haven't tried this with the current version, 6.52, it wasn't feasible in
earlier versions.
If I understand your formulation correctly, you are offsetting the
parameters back not forward. Does this give the same or similar results as
Williams?
