到目前為止，我們都是直接用群益期貨API內附的範例程式來手動執行取得報價或是下單，但我們的目標應該是要打造一組程式可以自動登入並完成交易，所以接下來我們要嘗試讓程式自動化，不用再手動輸入帳號密碼，並點選那些按鈕。

另外群益期貨API範例程式是偏好有視窗GUI介面，但有GUI介面就會需要多處理一些視窗元件顯示的程式，我們先簡化掉這些視窗GUI介面顯示的處理程式。

我們參考TFOrder.py複製相關程式碼到一個新的空白檔案，可以先存檔為Test.py，將原本的這兩行
richTextBoxMessage.insert('end', msg + "\n")
richTextBoxMessage.see('end')
都標上#號註解，改用這行取代
print(msg)

另外要注意到沒有GUI程式，即便能正常接收訊息，如果沒有做任何取出訊息的動作，訊息會卡在Message Queue裡面。因此我們要使用pywin32套件裡pythoncom模組包含的PumpWaitingMessages()將獲取到的訊息，從Message Queue裡面取出並利用。
