If you want to learn something, you need to know where to find information. Books are perfect for it.
In this time and age, better than a book are the ebooks you can find for free on the internet. That's specially great for self-taught people how don't have access to books for financial or any other reason.
Disclosure: I highly recommend for you to buy the ebooks as soon as you're able to. Support the authors.
Library Genesis
One of the most classic and complete site to find books online. Just type what your looking for, search it. Click in one of the mirrors and "get".
Mobilism
Another great website to look for ebooks. For this one you need an account to have access to the download links. Here I find most of the books I can't find in another sites.
Booksee
This website is perfect to find ebooks in pdf. Pretty straight forward, search what you're looking for and click download.
BONUS: Traders Library
Here you can find the most diverse trading books. Price action, indicators, trading strategies, Elliot wave...
These are the sites I use the most. If you have any suggestion, leave a comment. Those were the sites I found most of my trading books, so if you're a trader, just go for it.
