Sidney,
Here is some code I wrote a while ago (before looping) in VBScript
that should do the job for you.
Bill
-------------
SetBarsRequired( 10000, 10000 );
EnableScript("VBscript");
Price1 = ((H+L)/2);
//Put your percentage in The Annual Percentage line ... 8% = .08,
20% = .20
<%
Price1 = AFL.Var("Price1")
myArray = AFL.Var("Close")
AnnualPercentage = .15
Per = (1+AnnualPercentage)^(7/(5*365))-1
Summ = 0
HiIndex = Ubound(Price1)
for i=0 to HiIndex
Summ = Summ + 1
Next
Price1(0)=1
for i=1 to Summ-1
'Price1(i) = 1+i
Price1(i)=Price1(0)*(1+per)^i
Next
AFL.Var("Price1") = Price1
'AFL.Var("Summ") = Summ
%>
Plot(Price1,"15%",4,4);
