Draw Horizontal Line

[warpinator]

Hi All,

I am new to Ninjascript, I am trying to draw a horizontal line at last close price:

protected override void OnBarUpdate()
{
//Add your custom indicator logic here.

// create custom Courier New, make it big and bold
NinjaTrader.Gui.Tools.SimpleFont myFont = new NinjaTrader.Gui.Tools.SimpleFont("Courier New", 12) { Size = 20, Bold = false };

double my_last_price =Close[0];

Draw.Line(this, "myLastLine", false, 50, Close[0], 0, Close[0], Brushes.Black, DashStyleHelper.Solid, 1);
}

No line was drawn, if I replaced Draw.Line() with:
Draw.HorizontalLine(this, "myTag" + 1, Close[0], Brushes.Black, DashStyleHelper.Solid, 1, true);
then there will be an horizontal line cross the whole chart window, I was hoping I am able to control the starting/ending points of the line

Not sure what I did wrong

Thanks so much.

Hello warpinator,

Thanks for your notes.

The Draw.HorizontalLine() method only take a single argument for the price you want to draw the horizontal line at. You cannot control the start point and end point of a horizontal line draw object.

Draw.HorizontalLine(this, "myTag", false, Close[0], Brushes.Black, DashStyleHelper.Solid, 1);would draw a black horizontal line on the chart window at the last Close price.

If you want to control the start point and end point of a line you would need to use the Draw.Line() method to draw a line drawing object on the chart window from a specific start point to a specific end point.

Further, keep an eye on the Log tab of the Control Center for any errors that might appear when testing the script.
