Hello there,
I want to learn about Technical Analysis. Can you recommend some online courses and books?
Many thanks.

Follow up the videos of this channel:
https://www.youtube.com/user/tradingwithrayner You will surely learn a lot. It might be particularly talks about other markets but when it comes to technicals then its just on the same aspect and just like what others do say where babypips and investopedia is also a good place for you to start up specially when you are really starting from scratch. Just some tip, it might be easy to understand
but you should practice these skills neither on a demo platform or via on real account with small amounts. Learning trading cant really be done on just 1 day. This would take years of trial and error.
