Scrolling 2 text widgets together

I am using the pack() Geometry Manager to place all of the widgets. I opted for the pack() Manager because it is ideal for placing widgets side by side or drop down position. Fortunately, in a text editor, I have all the widgets Placed next to each other or in descending order. It is therefore advantageous to the pack() Manager. We can do the same with the grid() manager also.

IB TWS Trading Platform in Python 8 outsideRTH

IB TWS Trading Platform in Python 8 outsideRTH

In this tutorial you will add a check box to your gui form window that will allow you to trade after hours and pre-market.

Add this variable to hold the variable for the checkbox just above the create widgets function.

self.my_outsideRTH = False 

Add this to the end of the create_widgets(self): function

        # create a check button box for outside RTH
        self.chkOutsideRTH = Checkbutton(f1, font=('', 10),
                                         text='OutsideRTH', variable=varOutsideRTH)
        self.chkOutsideRTH.grid(row=9, column=6)

  Add highlighted text to the buy(self): function and the sell(self): function

  def buy(self):
        self.symbol = varSymbol.get()
        self.quantity = varQuantity.get()
        self.order_type = varOrderType.get()
        self.limit_price = varLimitPrice.get()
        self.my_outside = varOutsideRTH.get() # add here
        the_outsideRTH = 0
        if self.my_outside == True:
            the_outsideRTH = 1
        self.place_market_order(self.symbol, self.quantity, self.order_type,
                                True, self.limit_price, the_outsideRTH) # add here

    def sell(self):
        self.symbol = varSymbol.get()
        self.quantity = varQuantity.get()
        self.order_type = varOrderType.get()

                                False, self.limit_price, the_outsideRTH) # add here

Add the variable my_outsideRTH to the highlighted areas in the place_market_order() function as shown below.

    def place_market_order(self, symbol, quantity, order_type, is_buy, limit_price, my_outsideRTH): # add here
        print (symbol, quantity, order_type, is_buy, limit_price)

                                        'USD')
 # tests if is buy or sell
        buysell = 'BUY' if is_buy else 'SELL'
        order = self.create_order(order_type, quantity, buysell, limit_price, my_outsideRTH)# add here
        self.tws_conn.placeOrder(self.order_id, contract, order)
        # increses the order id by one
        self.order_id += 1

Add the variable outsideRTH to the highlighted areas in the create_order() function as shown below.

    def create_order(self, order_type, quantity, action, limit_price, outside_Rth):    # add  outside_Rth 
        order = Order()
        order.m_orderType = order_type
        order.m_totalQuantity = quantity
        order.m_action = action
        order.m_lmtPrice = limit_price  
        order.m_outsideRth = outside_Rth                  # add order.m_outsideRth = outside_Rth 
        return order

Add this to the bottom where all the variables are for your window form widgets.

varOutsideRTH = StringVar(root, value=False)
