Hu Jcl,
some guys from this forum has asked me to present the Markowitz tools you have presented here:
http://www.financial-hacker.com/get-rich-slowly/#more-1702
In the forum adapting it to the Italian market.

May I do it? Naturally it will be clear that all the work comes from you and all the link for downloading Zorro and the scripts will be the official ones.
Basically I will translate/copy/comment some piece of your posts/code and adapt your script to download data and analyze ETFs available on Borsa Italiana.

May I proceed?
Thank you
