How to instantiate a custom drawing object/tool

[trendisyourfriend]

Hi all,

In a strategy i am developing i'd like to be able to create/instantiate drawing objects based on a custom drawing tool. I have not found a way to do it similar to what it is possible with native drawing objects.

For example, with native drawing tools you can create or instantiate an object like this:
NinjaTrader.NinjaScript.DrawingTools.Line _myLine;
_myLine = Draw.Line(this, "target_" + _drawLine.plotName, false, 20, _priceLevel, 1, _priceLevel, markerColor, DashStyleHelper.Solid, 5);

But with a custom drawing tool i have no idea how to proceed or if it is even possible.

The only solution i found was to simulate a hotkey pressed using this command:
System.Windows.Forms.SendKeys.SendWait("%{3}"); // simulate Alt+3 pressed

But it is not perfect.

Are there any other solutions ?

Hello trendisyourfriend,

Thank you for your post.

I suggest checking out the ChartMarkersPlus script from the User App Share. It demonstrates how to add NS methods to draw the markers via other scripts; utilizing this idea in your custom drawing tool, you should be able to use the methods in other scripts to create/instantiate the drawing objects in other scripts, such as your strategy.

The ChartMarkersPlus script is publicly available on our NinjaTrader Ecosystem website:

Here is a basic guideline of how to import NinjaScript add-ons in NinjaTrader 8:

Note — To import NinjaScripts you will need the original .zip file.

To Import:

1. Download the NinjaScripts to your desktop, keep them in the compressed .zip file.
2. From the Control Center window select the menu Tools > Import > NinjaScript Add-on...
3. Select the downloaded .zip file
4. NinjaTrader will then confirm if the import has been successful.

Critical - Specifically for some NinjaScripts, it will prompt that you are running newer versions of @SMA, @EMA, etc. and ask if you want to replace, press 'No'

Once installed, you may add the indicator to a chart by:

• Right-click your chart > Indicators... > Select the Indicator from the 'Available' list on the left > Add > OK

Here is a short video demonstration of the import process:

• Install a 3rd Party Indicator or App

Please let me know if I can be of further assistance.
