What are your favorite advanced online class about volatility trading and forecasts?

Hi!

I work as a front-office developer for an exot desk. I am currently switching companies and therefore I have three weeks off that I'd like to dedicate to improve my comprehension of what traders do and hopefully get new ideas of tools I can build for them.

I browsed online courses but I found it really difficult to get a course that's not too academic and that is not an introductory/beginner course.

If you guys have any idea of content/online classes that could help me on the following, I would love to hear them:

• Volatility trading
• Dynamic hedging
• Any good forecast class for volatility in python (GNARCH but also some other ML models)
• Data visualization tools in python (I am looking for an interactive visualization tool that traders could access and play with on their web browser)

Thanks a lot!
