Congrats on finishing the course!
If you search on Youtube for “switching from forex to futures”, you’ll find some videos explaining the differences that you’ll need to account for. Sorry I don’t have links to specific videos.
Analysis wise, a chart is a chart so there isn’t really a leap in that aspect.
What to do next really depends on the method you plan on using for trading, but Smart Risk (on Youtube) has some good content and they don’t push a course down your throat. Avoid trading videos that lead with high end sports cars or stacks of money.
Some books that might be useful:
Any of the books by Al Brooks
Naked Forex
Three Lines: Forecasting Price Action
Good Luck!
