Sorry should have put in the way I found to do it
I recalled that timeframe functions compress the data into the last
bars of the chart, so I had to start the loop from the first bar of
the actual weekly data within the daily chart bars
numweeks = LastValue( Cum( DayOfWeek()>Ref(DayOfWeek(),1) ) );
TimeFrameSet(inWeekly);
//x[BarCount-numweeks-1]=C[BarCount-numweeks-1];
x[0]=C[0];
//for(i=1;i<BarCount;i++)
for(i=BarCount-numweeks;i<BarCount;i++)
{
if(C[i]>x[i-1])
{
x[i]=C[i];
}
else
{
x[i]=x[i-1];
}
}
TimeFrameRestore();
xx = TimeFrameExpand( x, inWeekly );
Filter=1;
AddColumn(C,"close",1.3);
AddColumn(x,"x",1.3);
AddColumn(xx,"xx",1.3);
