StocksMA is a package to facilitate access to financial and economic data of Moroccan stocks.

Hello 👋

First of all thanks for the amazing work on this library. My PR is a quick contribution to add support for overall session performance. A feature that I needed to have on another project.

I added two new methods get_best_performers() and get_worst_performers() based on Medias24's API (Parent company of LeBoursier, although these endpoints were not available on LeBoursier for some reason).

The output of each method is a dataframe object that has either the top or worst performers given a date string.

The README was updated to reflect the new functions. Let me know if you think this is useful.

Drop commits where publish-package.yml file was created/edited (i.e f353245d031450f4329d02d8238fe6760a3a21f4 and 0df0b8f79e17b0fea0719c64dfde8647bdb9f917)

I followed the instructions on pypi and when running the following ligne: stm.get_price_data(['CIH','maroc telecom', 'involys'], start_date='2020-11-14', end_date='2022-02-14')

I get this error:
