I am currently using TD Ameritrade's Think or Swim platform to manage a portfolio that consists of mostly stocks/etfs/mutual funds with a few bonds. I'm trying to figure out a way to automatically record my account balance on a daily or weekly basis so I can view/graph my portfolio performance. Is there a method to auto export this data to excel? Are there some good/cheap programs/utilities that can do this for me? Thanks for any input -MD
