Hi Chris,
Indeed work your way trough the school. Less than 4% of the trader that start the school do actually finish it, so prepare to see if you have the dedication to put sugnifincant time in your education(hundreds-thousands of Hours).
From your name I assume that you understand dutch, so the book ‘leren traden’ by Steven Anthonis might be nice for you to read (I am still thankfull that was my first trading book). From that point there are many good english books. I reccomend ‘trading beyond the matrix’ by van K Tharp and all his other books. As for websites, try to focus on free education courses. I find the babypips school better than most other websites on education even though its free.
As for a broker I started off at plus500 aswell, but I changed to brokers offering the MT4 platform, so I was anble to use my technical analysis better ( fibbonaci levels). Also a lot of other brokers offer lower trading costs (spread,commission etc.) During the pipsology school you will learn about how to choose a broker.
I know you will get ‘sucked’ into the charts quite often, but please give yourself some time, and don’t be to hard on yourself if you make mistakes(every trader makes the typical beginner mistakes).
Dedicate at least 3 months on education, then at least 6 months on education+demo trading before considering going live.
Good luck on your journey!
