Can I change a button text OnBarUpDate

[cre8able]

I have 2 button on my ChartTrader that I use to place orders.

I stole the code from you guys and create the buttons in State.Historical.

            else if (State == State.Historical)
            {
                if (ChartControl != null)
                {
                    ChartControl.Dispatcher.InvokeAsync(() =>
                    {
                        CreateWPFControls();
                    });
                }
            }
​ 

I do the button content and background in the method that creates the buttons






I would like to change the button content and background depending on conditions on the chart.

I tried placing this in OnBarUpdate()

            buttonsArray[2].Background    = Brushes.Blue;
​ 

that didn't work.

Is it possible to change the buttons during execution?

if so, how?

thanks

Hello cre8able,

Yes you can do that using the variable. you need to use a dispatcher:

if (ChartControl != null)
{
ChartControl.Dispatcher.InvokeAsync(() =>
{
buttonsArray[2].Background = Brushes.Blue;
});
}

I unsuccessfully tried this

        private void UpdateButtonColor(Brush color)
        {
            if (buttonsArray[2] != null)
            {
                ChartControl.Dispatcher.InvokeAsync(() => buttonsArray[2].Background = color);
            }
        }
        
        
#region===        OnOrderUpdate    //%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%    
        
        protected override void OnOrderUpdate(Order order, double limitPrice, double stopPrice, int quantity, int filled, double averageFillPrice, OrderState orderState, DateTime time, ErrorCode error, string nativeError)
        {
            // Handle entry orders here. The entryOrder object allows us to identify that the order that is calling the OnOrderUpdate() method is the entry order.
            // Assign entryOrder in OnOrderUpdate() to ensure the assignment occurs when expected.
            // This is more reliable than assigning Order objects in OnBarUpdate, as the assignment is not gauranteed to be complete if it is referenced immediately after submitting
            if (order.Name == "Long" || order.Name == "Short")
            {
                entryOrder = order;

                // Reset the entryOrder object to null if order was cancelled without any fill
                if (order.OrderState == OrderState.Cancelled && order.Filled == 0)
                {
                    entryOrder = null;
                    sumFilled = 0;
                }
            }
            
            if (Close[0] > Open[0])
                UpdateButtonColor(Brushes.Blue);
            else
                UpdateButtonColor(Brushes.Yellow);
                
        }

Hello cre8able,

What was unsuccessful?

I would suggest looking at the following file, that shows how to toggle buttons based on conditions.
