Hi Don ,

This is what I use: 


//=================================================
//PF CHART GRID CONSTRUCTION
//==================================================


Class = ParamToggle("AssetClass", "Stocks|Forex", 1);
PlotGridLines = ParamToggle("PlotdGrid", "Yes|No", 0);
if (PlotGridLines)
{
	begin = SelectedValue(BarIndex());
	end = LastValue(BarIndex());
	period = end-begin +1;

	if( begin<end)
	{
		ScreenHigh =LastValue( HHV(cl, period )) + box;
		ScreenLow =LastValue( LLV( Cl, period) )-box;
		shift = 7;
		top= LineArray( begin-shift, screenHigh, end, screenhigh, 0 , 1);
		Bot= LineArray( begin-shift, screenlow, end, screenLow, 0, 1);
		Plot( top, "", gc,styleLine|styleNoLabel , 0, 0,shift);
		Plot( bot, "", gc,styleLine|styleNoLabel,  0 , 0 , shift);
		
		// Vertical Grid 
		VerticalGrid = IIf ( BarIndex() >= begin, IIf(direction==1,
screenHigh, screenLow), Null);
		Plot (VerticalGrid, "", gc, styleStaircase|styleNoLabel, 0,0, 1);
		
		// Horizontal Grid 
		format =IIf(Class, 8.2,  IIf (StrRight(Name() ,3) == "JPY", 8.2, 8.4));
		while ( LastValue(bot)< LastValue(top)-0.5*box)
		{
			Plot(  bot , "", gc, styleLine|styleNoLabel, 0, 0 ,shift);
			text = NumToStr(LastValue(bot) + 0.5*box, format);
			xposition = BarCount+2;
			yPosition = LastValue(bot)+0.27*box;
			PlotText(text,  xPosition , yPosition, colorWhite);
			bot = bot + box;
		}	
	}

}
