I would like to develop an app that shows one chart that contains multiples stocks simoultaneously taken from yahoo finance. The flow should be the following:
Choose the stocks from checkboxes;
Press a button that load into a list each stock checked;
Download from yahoo finance the time series of the stock selected and print in one chart
My issues are that I don’t know how to convert into a list all the checkboxes ‘checked’ and how to do a button that trigger it and then download the data.
