the
new comments in the help make this far clearer to an average user like myself
than does the c++ code. I also appreciate the examples with for looping and AMA.
The more examples we see the clearer the use and value of these additions
become.

if you expect the X user reading your<A

internally is implemented via EMA:Len=10;Graph0= 2 * EMA( C, len ) -
EMA( EMA( C, len ), Len );// for comparison
onlyGraph1=DEMA(C,Len);and immediately understands all these
explanations/calculations, then you address to quite advanced
users.Leave your <A

without any further comment, it will be OK for everybodyand we will be
