Listing 4.7

[jobquiroz]

Hello,
I'm trying to run the simulator example usage in listing 4.7 but I get a "Value error: Lenghts must match"

When I print the lengths of the variables c_series and p_series in _compute_equity_series (within the PortfolioHistory class) I indeed find out that they are different (1280 vs 2495).

I think I have all set up correctly, my example usage of PortfolioHistory runs correctly.

Do you have any advice?

Thank you.
The book is great.

Hi Job, please try running the simulate_portfolio.py script directly from the GitHub repo. It is the same as Listing 4.7, and I just verified it works on a clean copy of the repo.

Thank you, that actually worked pretty well!
