Nice piece of code and why it doesn't work in jscript?
EnableScript ( "jscript" );
bars = Optimize( "param", 14, 5,40, 1 );
LinReg=LinRegSlope( L, bars);
<%
function GetArray( Name )
{return VBArray( AFL( Name ) ).toArray();}
Lo = VBArray( AFL ("L" ) ).toArray();
Hi = VBArray( AFL ("H") ).toArray();
Cl = VBArray( AFL ("C") ).toArray();
Result= new Array;
Thisval =0;
Minval=0;
Count=AFL.Var ("bars");
LinReg= GetArray("LinReg");
//Function CalcIt( Low, LinReg, Count )
//Result = Low
function CalcIt( Lo,LinReg, Count)
{
//For i = 0 To 2*Count - 1
//Result( i ) = -1e10
for (i=0; i<(2*Count)-1; i++)
Result[ i ] = -1e10 ;
//empty Values for initial Count elements
//For i = 2*Count To UBound( Low )
//Minval = Low( i )
for (i=2*Count; i<Lo.lenght ; i++)
{
Minval = Lo[ i ];
//For j = 1 To Count -1
//ThisVal = Low( i - j ) + j * LinReg( i )
for (j=1; Count-1; j++)
{
ThisVal = Lo[ i - j ] + j * LinReg[ i ];
//If Minval > ThisVal Then Minval = ThisVal
If (Minval > ThisVal)
Minval = ThisVal ;
//Next
}
//Result( i ) = Minval
Result[ i ] = Minval;
//Next
}
//CalcIt = Result
//End Function
}
AFL("Result") = Result;
