Some very cool coding.
I liked Peak(1,x,.001) to define a line that resets at every new peak. Any
specific reason for using .001? (I note that the ZigZag function won't allow
a number less than .01)
Highest(If(pk=pk1,0,pk)) is very elegant as a way of defining a data array
excluding the highest value. I tend not to think of using highest() or
lowest() because they include all loaded data, but that's not a problem when
the data array is already restricted in time, as in this case.
Are there any issues surrounding the use of Peak() that I should be aware
of? I don't use ZigZag based functions much because of the problems.
I would like to change this into a dynamic band so I can see the effect over
time. I'll take a crack at it myself first, but any hints welcome!
Thank you Jose
Andrew

Easier said than done.
Difficulties involved:
1) Restrict peaks/troughs lookback to last 6 calendar months;
2) Find highest / 2nd highest / third highest/lowest peaks/troughs;
3) Get it coded into MetaStock without using the professional services
of a competent programmer. ;)
Try this:
====================
Peak/Trough averages
====================
---8<---------------------
{ Average of three highest peaks / lowest
troughs in an oscillator over last 6 months }
{ CCopyright 2005 Jose Silva

{ Oscillator/Indicator }
x:=MACD();
{ User input }
lbMth:=Input("Lookback months",1,12,6);
{ Restrict search to lookback period } StMnth:=LastValue(Month())-lbMth;
StYear:=If(StMnth<1, LastValue(Year())-1,LastValue(Year()));
StMnth:=If(StMnth<1,StMnth+12,StMnth);
lookback:=Year()>StYear
OR (Year()=StYear AND (Month()>StMnth
OR Month()=StMnth
AND DayOfMonth()>=LastValue(DayOfMonth())));
{ Highest/2nd/3rd peak values } pk:=If(lookback,Peak(1,x,.001),Lowest(x));
pk1:=LastValue(Highest(pk)); pk2:=LastValue(Highest(If(pk=pk1,0,pk)));
pk3:=LastValue(Highest(
If(pk=pk1 OR pk=pk2,0,pk)));
{ Lowest/2nd/3rd trough values }
tr:=If(lookback,Trough(1,x,.001),Highest(x));
tr1:=LastValue(Lowest(tr)); tr2:=LastValue(Lowest(If(tr=tr1,0,tr)));
tr3:=LastValue(
Lowest(If(tr=tr1 OR tr=tr2,0,tr)));
{ Average of last 3 peak/trough values } avgPk:=(pk1+pk2+pk3)/3;
avgTr:=(tr1+tr2+tr3)/3;
{ Plot in own window }
x;avgPk;avgTr
