Original post:

While we wait for the IB credentials for a paper trading account, let's start with build a Graphical User Interface that will wrap the code that will fetch prices from IB TWS.

We will use kivy as it's cross-platform, based on python, and well-maintained.

Steps

• [x] build the hello world application documented on kivy's home page (~1h)
• [x] start a new kivy application that will have (~5h)
  • main menu will be just 3 buttons: prices, portfolio, trades
  • when prices is clicked, it should display a pandas dataframe
  • let's use import pandas as pd; df = pd.DataFrame({'symbol': ['a','b','c'], 'close': [100, 120, 90]}) for now
  • when portfolio is clicked, it should show another pandas dataframe
  • let's use import pandas as pd; df = pd.DataFrame({'symbol': ['a','b','c'], 'position': [1,2,3]}) for now
  • when trades is clicked, it should show another pandas dataframe
  • let's use import pandas as pd; df = pd.DataFrame({'symbol': ['a','b','c'], 'qty': [1, -1, 0]}) for now
