Hi Graham,
I forgot to include the PivotLow function on the last send. Both are below. You'd use the functions like this:
#pragma nocache
#include "Wherever you put your afl file with the functions"
PH = PivotHigh(3,3); PL = PivotLow(3,3);
Plot( C, "C", colorLightGrey, styleBar+styleNoLabel );
Plot( PH, "res", colorRed, styleDots+styleNoLine );
Plot( PL, "sup", colorGreen, styleDots+styleNoLine );
Title = Name() + ", " + Date() + ", Support & Resistance Levels Support = "
+ PH + ", Resistance = " + PL ;
If you are using functions embedded in your afl, make sure they are above the code that actually calls them.
e.g.
Function Blah(Len);
{
return MoreBlah;
}
BL = Blah(5);
Plot(BL,"BL",colordefault,styleline);
Hope this helps,
Gary
CODE BELOW FOR THE PIVOT LOW/HI FUNCTIONS
//===== PivotHigh(LeftStr, RightStr) ====================================
/*
SUPPORT & RESISTANCE LEVELS
Graham Kavanagh 9 Oct 2003
Returns High value of pivot
*/
function PivotHigh(LeftStr, RightStr)
{
//Find turning points
top = H == HHV(H,LeftStr+1) AND H == Ref(HHV(H,RightStr+1), RightStr);
topH = ValueWhen(top,H);
return topH;
}
//======= PivotLow(LeftStr, RightStr) ====================================
/*
SUPPORT & RESISTANCE LEVELS
Graham Kavanagh 9 Oct 2003
Returns Low value of pivot
*/
function PivotLow(LeftStr, RightStr)
{
//Find turning points
BOT = L == LLV(L,LeftStr+1) AND L == Ref(LLV(L,RightStr+1), RightStr);
BOTL = ValueWhen(BOT,L);
return BOTL;
}

Thanks Gary That makes it interesting as I have not yet tried the function function :) Do you just put the numbers you want into the intital function setting Eg function PivotHigh(2, 4)Cheers,Grahamhttp://groups.msn.com/ASXShareTradinghttp://groups.msn.com/FMSAustralia-----Original Message-----From: Gary A.
