[amibroker] Re: Do Loop can not work if Initial value begin from middle of the data range

["wongloktim" <wlt@xxxxxxxxxxxxxx>]

It work If you Change to
return Hlow;
}
Start = SelectedValue(BarIndex());
Price=ValueWhen(BarIndex()==start,L,1);
Test=HigherLow(Start,Price);
Plot(IIf(start,Test,Null),"StopLoss",colorRed,4);

But it cannot work If you write as
return HlowArr;
}
Start = SelectedValue(BarIndex());
Price=ValueWhen(BarIndex()==start,L,1);
Test=HigherLow(Start,Price);Plot(IIfPlot(IIf
(start,Test,Null),"StopLoss",colorRed,4);

I doubt that Do Loop can not initial from the middle of the data 
range
