Is it possible to draw objects on chart through AddOn?
I want to add some support/resist line, fibonacci etc. to charts through Addon, I know indicator can draw objects on chart, but I am not sure how to do it through AddOn...yes, I know how to get the ChartControl, but what's next step? -
Hello,
Thank you for the question.
There are no documented ways to add Indicators or Drawing objects to a chart from an addon currently.
One way to add DrawingObjects specifically could be the following two items. One is a way to enact the Drawing "pen" tool for the object of your choice. the other would be in the case you have the instance of an indicator, you could supply it as the Base to draw an object like you would using NinjaScript.
Code:ChartControl.TryStartDrawing("NinjaTrader.NinjaScript.DrawingTools.ArrowDown");
The second would be to call the Static Draw methods like you would from an indicator, again this assumes you have a instance to the Indicator to provide a base:
Code:NinjaTrader.NinjaScript.DrawingTools.Draw.ArrowDown(indicators_instance, "test", true, 0, 2000, System.Windows.Media.Brushes.Red);
I look forward to being of further assistance.JesseNinjaTrader Customer Service
