Text Under Bar

[algospoke]

I am creating an indicator that will show a blue Up Arrow under the bar, have text saying "Buy Signal" under it and provide sound. I can get the blue Up Arrow to show on the chart but can't get the text to show underneath. Below is my code. What am I doing wrong?

if(High[2]>High[1] && Low[2]<Low[1])
{
Draw.ArrowUp(this, "Buy Signal" + CurrentBar, true, 0, Low[0] - 3 * TickSize, Brushes.Blue);
PlaySound(NinjaTrader.Core.Globals.InstallDir + @"\sounds\Alert1.wav");
}

Hello algospoke,

Thanks for your post.

The Draw.ArrowUp() method only draws an up arrow on the chart. It does not draw text on the chart.

Where you are passing in "Buy Signal" is the Tag parameter of the Draw.ArrowUp() drawing object being drawn on the chart. This is not text that appears on the chart.

You would need to call the Draw.Text() method in your script one line after the Draw.ArrowUp() method to draw text on the chart when an arrow is being drawn on the chart.

Please see the help guide documentation below for more information about Draw.Text().

Brandon,

I added the Draw.Text() but I still don't see any text on the chart. I only see the up arrows. See attached pic. Below is my code. What am I doing wrong?

Hello algospoke,

Currently, the text is being drawn 10 bars back from the current bar on the chart at the price of 1000.

You would need to modify the Draw.Text() method to have a unique tag name (similar to your Draw.ArrowUp() method), the barsAgo argument should be set to 0, and you would need to make sure you are using a price below the bar (such as Low[0] - 6 * TickSize).

See this help guide page for more information about Draw.Text(): https://ninjatrader.com/support/help.../draw_text.htm

Brandon - Awesome that worked! Appreciate the help
