Hi Preston
I really appreciate on your effort. I got some questions in regards
to DMX that you have code
1. could it be possible that the smoothing moving average
exponential argument be changed into weighted moving average
2. if the above mentioned can be changed why at this section
PDX:=ExtFml("ForumDll.VarMOV",Up,pds,E);
MDX:=ExtFml("ForumDll.VarMOV",Dw,pds,E); can not be changed. if I
change this into W the error message appear on the text. this
formula is the second formula from 2 types of the given formula
Again, thanks for your advance knowledge in coding
Regards
Adam
