I would like to start doing research first. My question is where can I read about how the research notebook works?
For any given date, I would like to look at the constituents of SPX. See if there is an analyst upgrade or down grade. If so I would like to store the 1 day, 1 week and 1 month return. And store the data in a file. The file does not need to be local, I can be stored on Quantopian servers.
Then I would like to write functions to make different kinds of plots. Can this be done?
