Drawing on panel 2 from strategy

[kanjy]

Hi there!

I am attempting to draw some lines on the second panel in my strategy, currently attempting this with OnRender as I was unable with regular drawing tools. The second panel is a different instrument to my first panel.
When I run the following code from one of your help guides:

[COLOR=#0000ff]protected[/COLOR][COLOR=#ffffff] [/COLOR][COLOR=#0000ff]override[/COLOR][COLOR=#ffffff] [/COLOR][COLOR=#0000ff]void[/COLOR][COLOR=#ffffff] [/COLOR]OnRender(ChartControl[COLOR=#ffffff] [/COLOR]chartControl,[COLOR=#ffffff] [/COLOR]ChartScale[COLOR=#ffffff] [/COLOR]chartScale)
{
[COLOR=#ffffff]  [/COLOR][COLOR=#008000]// Print the number of panels currently displayed on the chart[/COLOR]
[COLOR=#ffffff]  [/COLOR]Print(String.Format([COLOR=#800000]"There are {0} panels on the chart"[/COLOR],[COLOR=#ffffff] [/COLOR]chartControl.ChartPanels.Count));[COLOR=#ffffff]  [/COLOR]
}
​

I am able to display that that I have 2 panels loaded.
I assumed that I would be able to run the following code to draw on each panel respectively according to their chart index:

 if (this.ChartPanel.PanelIndex == 0) // NQ Panel
 {
     RenderTarget.DrawLine(startHighNQ, endHighNQ, brushNQ, 2); // High NQ
     RenderTarget.DrawLine(startLowNQ, endLowNQ, brushNQ, 2); // Low NQ
 }
 if (this.ChartPanel.PanelIndex == 1) // ES Panel
 {
     RenderTarget.DrawLine(startHighES, endHighES, brushES, 2); // High ES
     RenderTarget.DrawLine(startLowES, endLowES, brushES, 2); // Low ES
 }​

However, this is not the case. Is there another way I can approach accessing PanelIndex 1?

Thanks in advance

Hello kanjy,

Drawing into multiple panels is not something the strategies OnRender can do, that applies to its panel only. You would have to have a indicator added to the chart into the second panel and then that indicator could draw there. You can find a sample of a strategy that uses indicators for the purpose of drawing in multiple panels here: https://ninjatrader.com/support/help..._a_ninjasc.htm
