Identifying drawing Tools in Strategies

[Richardmm]

Hi,
I am developing a strategy, I add some drawing tools to my strategy (Horizontal line) and it works perfectly. However, when I add a horizontal line while the strategy is running, it cannot be identified in the strategy. Does exist any form that the strategy can identify horizontal lines without restarting the strategy?

 protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
        {
            base.OnRender(chartControl, chartScale);

            foreach (DrawingTool draw in DrawObjects)
            {
                if (draw is DrawingTools.HorizontalLine)
                {
                    DrawingTools.HorizontalLine line = (DrawingTools.HorizontalLine)DrawObjects[draw.Tag];

                }
            }
       }

This the code that i have to identify the drawing tools on the Onrender method.

Regards.

Hello Richardmm,

Thank you for the post.

Kindly see this indicator that labels all horizontal lines on the chart. This indicator's OnRender method has what you will need to get all horizontal lines on the chart.

We iterate through the ChartPanel's ChartObjects to find the horizontal line.

Here is a stripped down version of the logic used to detect horizontal line objects:

protected override void OnRender(ChartControl chartControl, ChartScale chartScale)
		{
			foreach (Gui.NinjaScript.IChartObject thisObject in ChartPanel.ChartObjects)
		  	{
			  
			  if(thisObject is NinjaTrader.NinjaScript.DrawingTools.HorizontalLine)
			  {
			  	 HorizontalLine l1 = thisObject as NinjaTrader.NinjaScript.DrawingTools.HorizontalLine;
				 Print("Found a horizontal line");
			  }
			}
		}
