IB TWS Trading Platform Python 6

In this tutorial we will request account updates and receive the position size and average price of our position. Create 2 labels and 2 text boxes (entry box)

        #create label for Average Price
        self.label22 = Label(f1, font=myFont, text='Avg Price', width=8 )
        self.label22.grid(row=6, column=3)

        #create label for Position
        self.label23 = Label(f1, font=myFont, text='Position', width=8)
        self.label23.grid(row=7, column=3)

 #create entrybox (textbox) for Average Price
        self.tbAvgPrice = Entry(f1, font=myFont, width=7, textvariable=varAvgPrice)
        self.tbAvgPrice.grid(row=6, column=4)

        #create entrybox (textbox) for Position size
        self.tbPosition = Entry(f1, font=myFont, width=7, textvariable=varPosition)
        self.tbPosition.grid(row=7, column=4)

  Add this to the server_handler function under "updatePortfolio"

            self.position = msg.position
            self.average_price = msg.averageCost

  Add this under the monitor_position function

        # '%.2f' = formats to 2 decimal places
        varAvgPrice.set('%.2f' % self.average_price) 
        varPosition.set(self.position)

add this to the bottom of the onEnter function

        varPosition.set('0')
        varAvgPrice.set('0.00')

  Add this near the bottom with the rest of the StringVar variables

varAvgPrice = StringVar(root, value='0.00') # variable for average price
varPosition = StringVar(root, value='0')  # variable for Position and set default to zero

All of the code up to tutorial 6

Trading platform in Python 4

IB TWS Trading platform in Python

In this tutorial we will

1. add some methods or functions for requesting streaming data
2. add events to the combobox
3. change text from lowercase to upper case
4. select all text in combobox
5. add items to the drop down list

Uncomment out these 2 lines of code in the widgets function under the combo box widget the one that is called cbSymbol combobox symbol

     self.cbSymbol.bind('<Return>', self.cbSymbol_onEnter) #when the enter key is press an event happens 
     self.cbSymbol.bind('<<ComboboxSelected>>',self.cbSymbol_onEnter) 

  add these two variables under """ initialize the frame"""

     self.account_code = None
     self.symbol_id, self.symbol = 0, 'AAPL'

  Add this to the connect_ to_tws  function

     self.register_callback_functions()

  add all these functions to your Python program.  Added some extra code that was not covered in the YouTube video that is highlighted in yellow.
