[EquisMetaStock Group] Coding problem

["Andrew Tomlinson" <andrew_tomlinson@xxxxxxxxxxx>]

Hi guys,

I am playing with a number of different ways of projecting a centered moving
average up to the current bar. For example, here I have a 9-day moving
average which is centered and therefore plots 5 days prior (i.e. the value
for a particular bar is the SMA that would normally plot 5 bars later). In
this case I am trying to continue the line plot using the result of
successively shorter centered moving averages.

The problem is that the following just plots the original centered moving
average (CMA). If I replace the CMA1, CMA2...etc. in the CMAP code with
numbers, they all plot, so the basic mechanism seems ok. I suspect I'm
making some kind of elementary mistake - can anyone see what I'm missing?

(I know there are forward references - try coding a centered MA without) 

P1:=Input("Odd # of bars:",1,1001,9);
MA:=Mov(C,P1,S);
CMA:=Ref(MA,(p1+1)/2);
CMA1:=Ref(Mov(C,P1-1,S),(p1+1)/2-1);
CMA2:=Ref(Mov(C,P1-2,S),(p1+1)/2-2);
CMA3:=Ref(Mov(C,P1-3,S),(p1+1)/2-3);
CMA4:=Ref(Mov(C,P1-4,S),(p1+1)/2-4);
CMA5:=Ref(Mov(C,P1-5,S),(p1+1)/2-5);

CMAP:=
If(Cum(1)=LastValue(Cum(1)-(p1+1)/2+1),CMA1,
If(Cum(1)=LastValue(Cum(1)-(p1+1)/2+2),CMA2,
If(Cum(1)=LastValue(Cum(1)-(p1+1)/2+3),CMA3,
If(Cum(1)=LastValue(Cum(1)-(p1+1)/2+4),CMA4,
If(Cum(1)=LastValue(Cum(1)-(p1+1)/2+5),CMA5,CMA)))));CMAP;

Best
Andrew
