Can anyone please help me with this indicator.
I want to plot a weighted moving average
e.g. fwma(3 period Close)= (C+2(Ref(C,-1))/3+1(Ref(C,-2))/3)/3 or
(Close(today) + 2/3xClose(yesterday) + 1/3xClose(two days ago))
divided by three;
(see fwma, below) but would like to be able to to do it by just
putting in the time period rather than doing these calculations
manually and can't figure out how to program it. Could be a bit time
consuming if I wanted to do a 200 period fwma. In the case below the
period is 12.
The WMA function in Amibroker gives a different result than my fwma.
Many thanks if you can help.
Larry.
fn1=ROC(C,T1);
fwma=(fn1+11*(Ref(fn1,-1))/12+10*(Ref(fn1,-2))/12+9*(Ref(fn1,-
3))/12+8*(Ref(fn1,-4))/12+7*(Ref(fn1,-5))/12+6*(Ref(fn1,-6))/12+5*(Ref
(fn1,-7))/12+4*(Ref(fn1,-8))/12+3*(Ref(fn1,-9))/12+2*(Ref(fn1,-
10))/12+(Ref(fn1,-11))/12)/12;
