It would be better, before the exercise, to check the formula you use.
a.
In your basic
result = ((i-1)/i)*result + (1/i)*Ref(C,-(i-1)) ;
"result" can not be in both sides of the definition.
On the other side, a simple MA is not a recursive function.
For the simple MA(C,3) the last value is
M0=(C0+C1+C2)/3
The previous value is
M1=(C1+C2+C3)/3
As you see, C0 is not included in M1 calculation.
b.
Since result is a function of i, there should be something like
result[i]=...
for the ith element of the result array
c.
there is a confusion in Ref(C,-(i-1)) .
The 801th element of a MA(C,3) in a 1000-bar Close array can not be a
function of the Ref(C,-(801-1)) or the Ref(C,-800) !!!
It would help to read the EMA, AMA analytic formulas from the HELP
manual.
