Why not plot the two versions rather than arguing whether they differ?

Subject: [amibroker] Re: Smothed Moving Average
I appreciate your comments but I am not convinced the code I posted
is a formula for MA(Close,N).
I am also aware that EMA, WMA, DEMA, TEMA etc. all exist, but from
the documentation I read (and can understand), thought this was
something different.
I hoped somebody better at math might recognize it.
