I am reasonably new to Metastock...am wondering is there a function like barssince that has the Nth occurrence option? Like Barssince(nth, expression)... I was kinda shocked that it didn't. I know of highestsincebars and such, but those functions just complicate what I am trying to do.
Thanks!

What about :
ValueWhen(nth, Expression,Barssince(something))

Wow..first of all thanks for the awesome direction...I still think this is convoluted...more than it needs to be..but here is what I did...using the last day of 2003 as an anchor in time...
myosc:= Fml( "My Oscillator");
now:=BarsSince( Year()=2003 );
firsthump:=ValueWhen(1,threeten =Ref(HHV(myosc,6),3),BarsSince( Year()=2003 ));
2ndhump:=ValueWhen(2,threeten =Ref(HHV(myosc,6),3),BarsSince( Year()=2003 ));
barssincefirst:=now-firsthump;
barssincesecond:=now-2ndhump;
And so now I know the bars since the last two humps of this oscillator occurred....that is what I was looking for.
Close?

Not sure what you are trying to accomplish #-o
But I will offer these changes :D
myosc:= Fml( "My Oscillator");
now:=Cum(1);
firsthump:=ValueWhen(1,threeten =Ref(HHV(myosc,6),3),now);
2ndhump:=ValueWhen(2,threeten =Ref(HHV(myosc,6),3),now);
barssincefirst:=now-firsthump;
barssincesecond:=now-2ndhump;
...
What is threeten supposed to do ?
Ref(HHV(myosc,6),3) - this is a refrence in the future ... are you sure you do not want -3 instead of 3?

Aaaa...cum(1)...very cool...
oh I was half finished changing something when I pasted...sorry...threeten is an oscillator so instead of that "myosc" definition it is actually "threeten"
so I am defining peaks in that oscillator as a point that is higher than the surrounding two on either side...threeten =Ref(HHV(threeten,6),3)
the idea eventually is to define when the nth peak in the oscillator occurred and what the price was at that time...so I can get the geometry of the price action into some other formulas

Gotcha ... :D
I think that you should be able to work it from here.
My only concern is that reference( ... ,3 )
You should fix that.
Let me know if you need more help oz_pdt_010

??? Sorry I did not understand ?
Your reference is invalid and will give you false results.
You should try removing it and using this instead :
threeten =HHV(myosc,6)
