The addon does not run completely

[Powerbucker]

Hello,

I have a problem with an addon, which has a strange behavior. When I open ninja with the addon activated (as default addon), it does not execute all the code of the addon, it stops suddenly
If I then recompile the addon, it works correctly.

The problem is when it is executed when ninja is opened.

This is the source code, in the event when a chart type window is opened, I want to look for the account selector and the position selector to capture the events.

Then I want to customize the charttrader buttons.

This is the source code:

OnWindowCreated event:

protected override void OnWindowCreated(Window window)
{
// We want to place our AddOn in the Control Center's menus
NinjaTrader.Code.Output.Process($"{window.Title}", PrintTo.OutputTab1);

if (window is Chart chart)
{
ConfigureControls(chart);
}
}​

ConfigureControls function

private void ConfigureControls(Chart chartWindow)
{
NinjaTrader.Code.Output.Process("Configurecontrols", PrintTo.OutputTab1);

// this is the entire chart trader area grid
Grid chartTraderGrid = (chartWindow.FindFirst("ChartWindowChartTraderControl") as ChartTrader).Content as Grid;

NinjaTrader.Code.Output.Process("PASA1", PrintTo.OutputTab1);
quantityUpDown = chartTraderGrid.FindFirst("ChartTraderControlQuantitySelector") as QuantityUpDown;
if (quantityUpDown != null)
{
quantityUpDown.ValueChanged += OnQuantityValueChanged;
commonData.quantitySelected = quantityUpDown.Value;
NinjaTrader.Code.Output.Process($"quantityUpDown -> {commonData.quantitySelected.ToString()}", PrintTo.OutputTab1);
}

NinjaTrader.Code.Output.Process("PASA2", PrintTo.OutputTab1);
accountSelector = chartTraderGrid.FindFirst("ChartTraderControlAccountSelector") as AccountSelector;
if (accountSelector != null)
{
accountSelector.SelectionChanged += OnAccountSelectionChanged;
commonData.accountSelected = accountSelector.SelectedAccount;
NinjaTrader.Code.Output.Process($"accountSelector -> {commonData.accountSelected.DisplayName}", PrintTo.OutputTab1);
}

NinjaTrader.Code.Output.Process("PASA3", PrintTo.OutputTab1);

}​
​

Custom selectors events:

private void OnQuantityValueChanged (object sender, EventArgs args)
{
commonData.quantitySelected = quantityUpDown.Value;
NinjaTrader.Code.Output.Process($"quantitySelected -> {commonData.quantitySelected.ToString()}", PrintTo.OutputTab1);
}

private void OnAccountSelectionChanged (object sender, SelectionChangedEventArgs args)
{
commonData.accountSelected = accountSelector.SelectedAccount;
NinjaTrader.Code.Output.Process($"accountSelected -> {commonData.accountSelected.ToString()}", PrintTo.OutputTab1);
}​

This is the log that shows what the code does:

NinjaScript Editor
Chart - Chart
Configurecontrols
PASA1
quantityUpDown -> 0
PASA2
OnStateChange -> Terminated
quantitySelected -> 1
accountSelected -> XXXXXXXX​

The code stops between PASA2 and PASA3, after configure account selector event (accountSelector.SelectionChanged += OnAccountSelectionChanged), because the two events are fired.
I can see, in the middle of execution, the OnStateChange (Terminated) is fired.

If I compile the addon, runs OK


Could you help me?

Hello Powerbucker,

I recommend you start with a working script.

Copy this.

And in the copy modify the script to add your code one line at a time until the behavior returns.

The last added code is likely causing the behavior.

Below is a link to a working sample addon script to get you started.
