How can I know when the instrument is selected from the MainMenu?
The OnInstrumentChanged method is not called.
Like the example we have here:

https://ninjatrader.com/support/helpGuides/nt8/?instrumentselector.htm

// This method is fired when our instrument selector changes instruments
private void OnInstrumentChanged(object sender, EventArgs e)
{
Instrument = sender as Cbi.Instrument;
}

If you can give an working example, it would help a lot.
Tks!

Hello cassiano_sanches,

Thanks for your post.

From the window, you will have to find the InstrumentSelector from Automation ID. The Windows Kits inspect tool can be used to find Automation IDs. A publicly available link regarding the Windows Kits inspect tool can be found below.

Please see the attached example which demonstrates finding the Instrument Selector. Code is implemented in an indicator. If you need to loop through all open windows, you could do something like the following:

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;
}

We look forward to assisting.
