This is close, at least there's a plot and very similar to the
regular MA though not completely.
Btw it is not an exponential but a simple mov.avg. i was trying to
define. The "formula" sure is o.k., the problem is in the coding (in
mine).
At first sight I don't get why it is necessary to use the subscript
[], need some time to digest.
Should you run into the exact match please do post it. Appreciate
your help.
