How do I limit the length of an horizontal line?

[cryfgg]

The code below draws the horizontal line across the entire chart. However, i would like to limit the length to the last 20bars. Is there a way to do this.

if (UseExtendedLine)
{
// Draw.HorizontalLine(this, "Currprice", false, SLTPLineC, LineColor, LineStyle, LineWidth);
Draw.HorizontalLine(this, "Currprice1", false, Close[0]+SLTPLine1, LineColor1, LineStyle1, LineWidth1);
Draw.HorizontalLine(this, "Currprice2", false, Close[0]-SLTPLine1, LineColor1, LineStyle1, LineWidth1);
Draw.HorizontalLine(this, "Currprice3", false, Close[0]+SLTPLine2, LineColor2, LineStyle2, LineWidth2);
Draw.HorizontalLine(this, "Currprice4", false, Close[0]-SLTPLine2, LineColor2, LineStyle2, LineWidth2);
Draw.HorizontalLine(this, "Currprice5", false, Close[0]+SLTPLine3, LineColor3, LineStyle3, LineWidth3);
Draw.HorizontalLine(this, "Currprice6", false, Close[0]-SLTPLine3, LineColor3, LineStyle3, LineWidth3);

}

I tried using the draw.line code below, but it wasn't drawing the line on the chart.

Draw.Line(this, "CurrPrice7", false, 20, Close[0]+SLTPLine1, 0, Close[0]+SLTPLine1, LineColor1, LineStyle1, LineWidth1)

What am I doing wrong?

Hello cryfgg,

Thanks for your post.

Draw.HorizontalLine does not allow you to specify the number of bars back that you would like the line to start.

Instead, Draw.Line would need to be used if you want to specify the number of bars back that the line starts.

See the attached example script which demonstrates using Draw.Line to draw a line starting 20 bars ago.
