Accessing ChartWindow & ChartTrader in an add on

[manishj]

Hello world, my first post here. trying to create an Add on which is going to be used for disabling ChartTrader when account exceeds certain drawdown. I referred one of the WPFmodication example which ChelseaB has out for others to follow. it works great (its made as an indicator). I tired to use the same chartWindow snippet in my Add on but getting a compile error as

AddOnFramework.cs	The name 'ChartControl' does not exist in the current context	CS0103	543	52

here is my snippet where i am getting main chart & chartTrader.

private void performAccountGuardCheck(Account activeAccount) {

// get the main chart window
// the main chart window
chartWindow = System.Windows.Window.GetWindow(ChartControl.Paren t) as Chart;
// if not added to a chart, do nothing
if (chartWindow == null)
return;
// this is the grid in the chart window
chartGrid = chartWindow.MainTabControl.Parent as Grid;
// this is the entire chart trader area grid
chartTraderGrid = (chartWindow.FindFirst("ChartWindowChartTraderCont rol") as ChartTrader).Content as Grid;
//chartTraderGrid.IsEnabled = false; =

}

Not sure where i am going wrong.. all i need is access to Main ChartWindow and then get hold of ChartTrader object, please note that i am using an Add-on. thank you in advance.

Hello manishj,

Thank you for your post.

Since you're doing this from an addon instead of from an indicator which already knows which window you're referring to, you'd either need to loop through the active windows to find windows that have a chart or make a check in OnWindowCreated whether the newly created window is a chart and then get the ChartTrader from the Automation ID.

Here's an example of looping through chart windows:

foreach (var window in NinjaTrader.Core.Globals.AllWindows)
{
// check if the found window is a Chart window, if not continue looking
if (!(window is NinjaTrader.Gui.Chart.Chart)) continue;

window.Dispatcher.InvokeAsync(new Action(() =>
{
// try to cast as a Chart, if it fails it will be null
var foundChart = window as NinjaTrader.Gui.Chart.Chart;

// make sure we found a chart
if (foundChart == null) return;

// make sure the found chart is the owner window
if (foundChart != this.Owner as NinjaTrader.Gui.Chart.Chart) return;
}));
}

There's another example of getting all charts from an addon in this older forum thread here:

Your snippet was really helpful Kate. Got me what i wanted to a great extend. if there a way to get hold of followings now from Add-on.
1. Context Menu :
2. SuperDOM. any help here would be appreciated. i guess for superdoom i just need to follow superdomControl<wpeId>. as automation id ?

For context menu attaching a pic of what control i am trying to get hold of.

again thank you so much for prompt & helpful response.

Thank you for your reply.
