Simple indicator that prints the instrument name

[Grantx]

Hi,
See the screenshot. Is there an indicator that prints text for the current instrument on the chart and keeps it in the top left corner? I take a lot of screenshots and it would be handy to have something like this.
Thanks.

Jessica can you please tell me how to import this?
Thanks

[NinjaTrader_JessicaP]

I would be happy to.

1. Copy the attached file to (My) Documents\NinjaTrader 8\bin\Custom\Indicators
2. In NT8, New -> NinjaScript Editor
3. Press F5 to compile

The indicator is now installed and ready to be added to a chart

Is there a reason for placing the Draw.TextFixed methods in OnBarUpdate() as opposed to OnStateChange() if (State == State.Historical) ?

[NinjaTrader_JessicaP]

Just habit When I write very short simple scripts I tend to treat OnBarUpdate as my main entry point. I tend to view OnStateChange as a set-up routine. Your suggestion would be more efficient than mine which repeatedly draws the same symbol, as your suggestion would only draw this symbol once.

Would you be able to tell me how to import this to NT7 please Jessica?

Thanks

This tool was written for NinjaTrader 8, and would need to be re-written by yourself or a community member for NinjaTrader 7.

Hi Tradesmart, Jessica says that your way is more efficient. Could you tell me how to change to your suggestion?
Also (sorry Im being a bit picky here), how would I get the background to the default slategrey colour of Ninja?

[NinjaTrader_JessicaP]

The attached script contains a more efficient one-time execution (I needed to use State.Realtime instead of State.Historical to have access to all the index data that I use), and the final Brush, the background brush, has been changed to Brushes.Transparent from Brushes.Black.

This said, having run this script, I recommend using the original script if you run this one overnight. Since this only executes one time, the time never updates in this script, and so the date will not either. Comparing this script to the last one to see how to change the background to either Transparent or SlateGrey I will leave as an exercise to you. You can also use this more efficient form, replacing every instance of Time[0] by DateTime.Now .

You are my new favourite person Jessica. Thank you so much for doing this!

Hi, Jessica, can you advise how to get the text to show the tab name? I replaced Instrument.FullName with ChartControl.ChartTab.ActualTabName but it returned the error "Error on calling 'OnBarUpdate' method on bar 0: The calling thread cannot access this object because a different thread owns it."

Kindly assist. Thanks!

Hello Rainmakersg,

Thanks for your reply.

It is a thread/timing issue. You would need to use a dispatcher to pull the information in OnStateChanges State.RealTime. Reference: https://ninjatrader.com/support/help...-threading.htm

For example this works:

if (ChartControl != null)
{
ChartControl.Dispatcher.InvokeAsync(new Action(() =>
{
NinjaTrader.Gui.Tools.SimpleFont myBigFont = new NinjaTrader.Gui.Tools.SimpleFont("Lucida Sans Unicode", 24) { Size = 50, Bold = true };
NinjaTrader.Gui.Tools.SimpleFont myMediumFont = new NinjaTrader.Gui.Tools.SimpleFont("Lucida Sans Unicode", 18) { Size = 25, Bold = true };
Draw.TextFixed(this, "Line 2", "\r\n\r\n" + Time[0].ToString("dd/MM/yyyy"), TextPosition.TopLeft, Brushes.Silver, myMediumFont, Brushes.Black, Brushes.Transparent, 100);
Draw.TextFixed(this, "Line 1", ChartControl.ChartTab.ActualTabName, TextPosition.TopLeft, Brushes.Silver, myBigFont, Brushes.Black, Brushes.Transparent, 100);
}));
}
