There is no course of instruction that anyone can give you.
Nearly every trader follows the same path on his own.
First you will learn about indicators and think they are the best thing ever. You will see all these instances where they would have been profitable. Then you will realize they don't work either alone or in any combination.
Then you will look at other price pattern things like head and shoulders, cup and saucers, etc., and then you will realize those are no more reliable than indicators.
Then you will get pissed and give up for a while.
Then you will read about some other nonsense like Fibonacci levels or magic harmonics or whatever, but you will also realize that those don't seem to work in real time (although they sure look nice in hindsight!).
Then you will hear about "price action" but you will struggle for years to even get a definition of what that means despite hearing traders who claim to be profitable talking about how they only use price action.
You will encounter dozens of traders online who claim to be profitable yet never provide any proof and who also cannot give you direct answers to questions you may ask. They will also never make calls in real time, but they will be sure to post winning charts after the fact showing how they entered exactly at the bottom and sold exactly at the top! In the beginning you will see them as gurus, but eventually you will realize that 100% of them are just trolling people online and your BS detector will develop nicely as a result.
You will develop your own ideas... you will develop your own indicators, they will work better than the commercial ones you learned about when you were a beginner, but they still won't be profitable over time.
You will hear about things like grid trading and think holy crap... that is the holy grail... and then you will learn about the people who blew their account doing it.
Somewhere along the line you will get the genius idea that all you have to do to make money is take a losing system and reverse the buy and sell signals. You'll have dollar signs in your eyes. And then you will test it and realize that the opposite of a losing system is quite often still a losing system. This will cause you much internal struggle as it will make no sense.
Trading seems to be a field of stripping away what doesn't work. You must go through it yourself. I can tell you that I've backtested every commercialy available indicator and system in every possible combination and with every possible parameter and none of them is profitable, but you will not actually believe me when I tell you because you want to believe that something works. You must go through that path alone. It takes months/years before you are finally convinced that "nothing works" and once you finally realize that, THEN you have a framework in your mind for how to begin designing a system that may be profitable.
If you make it that far, you have a chance to be successful. If not, you will be like every other person who is still searching for that holy grail indicator, falling for the hype, and wasting their money on "gurus" who don't teach them anything quantifiable and indicators that don't work, as well as watching their account shrink from losing trades.
It's best if you use a practice account during these steps. Once you are consistently profitable for 3 months on a practice account, then you can start using a real account with small size. Beware, trading with a real account feels entirely different.
