I lot of people will say without any irony that online resources for learning forex are a bad idea. I don't really think the medium through which you educate yourself is as important as the quality of the education itself, and there lies the problem; if you are new to the trading racket and can't decipher good or bad advice as a result then how do you know what to choose.
I don't think it would be instructive to buy a how to guides that purports to teach you a particular method of trading that is successful, at the end of the day you have to find your own rhythm and what works for you considering your personality, skill set and what ever else.
In that case I would suggest that you instead seek to understand the market(s) better and how they work, the features that give each currency pair it's distinct personality for example and the macros behind the longer term trends. And not just on FX but other markets too, with a view to understand how everything fits together.
Maybe you have an indication that certain commodity prices will rise for whatever reason and that might have an impact on your FX trading for the commodity linked pairs. Who knows, and that is the fun, I think learning the markets is an educational pursuit for life.
Use well vetted introductory guides to gain a overview: https://www.bookdepository.com/ft-guides
and then move on to study the same literature that buy side investment professional read. check out the cfa courses and look for relevant content there https://www.cfainstitute.org/pages/index.aspx
or check the IFoA Investment A and Investment B.
Go on to the campus recruiting page of any global bank and look for the recommended reading list for candidates seeking Markets roles. I know Morgan Stanley used to have a very comprehensive list.
pick up the phone a call a trader (preferably buy side) and ask them what they would recommend.
And then ask them if they would lend you some money for your trading account; you never know.
