There are many sources to learn about trading and you can choose which one you need to learn at the early level. In this forum, you can find out some sources, mostly the basic knowledge about trading. For further knowledge, you may also need to learn from other sites, outside this forum. Anyway, you stated that you want to learn it slowly, but it is better if you make a plan or a specific target. I assume you don't want to spend all your time for learning only, you need to set a plan when you probably start your experience in trading. Not all knowledge can be found from theories, some knowledge can be obtained if you practice it.
