The were several posts recently about drawing thicker lines.
Attached is a code I wrote, using code snippets from TJ and comments from
Herman.
This code draws a line of variable thickness, for this sample code. Also it can
draw a line acroos entire screen of only part of it.
To see this code function, you must use a chart that covers price range of 80
to 85. (IBM)
The file suffix has been changed to ".txt". You must change it to ".afl" for
the code to work.

//This code draws a line of variable thickness, specified as percent of screen
//Two lines are shown: The first across entire length of screen, the second
over a specified segment.
//
//For this example code use a chart that has a price range around 85. (IBM)
//
//Use parameter to see changing thickness
thickness = Param("Thickness",5,1,20,1);
function ThickLine(Value,percent,Color)
{
//find max and min values of chart
barvisible = Status("barvisible");
upperrange = LastValue( Highest( IIf( barvisible, High, 0 ) ) );
lowerrange = LastValue( Lowest( IIf( barvisible, Low, 1e9 ) ) ) ;
Maxheight = (upperrange - Lowerrange) * percent / 100;
for (i=-5; i<5; i++);
{
j = Maxheight / i;
//
//Draw line across entire screen
V2 = Value - j/2;
V3 = V2 + j;
PlotOHLC(V2,V2,V3,V3,"",Color,styleCloud);
//
//Draw line for a segment of screen
V4 = V2 - 5;
V5 = V4 + j;
V6 = IIf(BarIndex() > BarCount - 30 AND BarIndex() < BarCount-10,V4,Null);
V7 = IIf(BarIndex() > BarCount - 30 AND BarIndex() < BarCount-10,V5,Null);
//
PlotOHLC(V6,V6,V7,V7,"",Color,styleCloud);
}
}
PlotOHLC(O,H,L,C,"",colorBlack,styleCandle);
thickline(85,thickness,colorBlack);
