Underneath code works fine for me :
Daysback = Param("Days Back",126,10,252,1);
FirstBar = BarCount - DaysBack;
YY = IIf(BarIndex() >= Firstbar,EndValue(Close),Null);
Plot(YY,"LastClose",colorRed,styleThick);
Plot(Close,"Close",colorBlack,styleCandle);
Regards, Ton.

Something like this:
start = <start bar index>
end = <end bar index>
val = <horizontal line value>
bix = Cum(1) - 1;
hline = IIf(bix >= start AND bix <= end, val, Null);
For the bar index, you could also use:
bix = BarIndex();
bix = bix - bix[0];
