Unfortunately, now not everything can be learned free of charge in a short period of time. So if you want to save time and learn something more, do not be afraid to spend money.
Gotta spend money to make money! Yeah, don't be afraid to try out a few of the courses that are available. You can find reviews on them if you dig deep enough. Unfortunately, most of the good ones are incredibly expensive. But that's the cost that quality comes with.
Another good option is using books from professional traders as reference, and then putting the techniques into practice and seeing which ones work best for you. There is no "golden strategy" or "one-size-fits-all" technique that will make profits all the time. A big part of learning is being adaptable to change, and recognizing why something didn't work.
