Portfolio & Portfolio.Invested not defined?

Hi All,

I am a new learner for Python quant. I am following a very simple strategy to learn. But during backtest, it either mentions "Portfolio not defined" or "Portfolio.Invested not defined". May I know how to solve it?

Thanks a lot. :)

Hi Yao,

Thanks for attaching the images. According to the code and the error message, the line:

Qty = Portfolio.Cash/data["SPY"].Close

 needs to be changed to:

Qty = self.Portfolio.Cash/data["SPY"].Close

The Portfolio property needs to be accessed by referencing QCAlgorithm using self. Good luck!
