Books/reading are important to get a solid foundation and understand the terminology. A couple online, free, resources are https://www.babypips.com/learn/forex and https://www.marketlifetrading.com/course/index. Maybe start there and then determine what market you want to trade, and what style you want to trade(long term, short term, trend following, mean reversion, etc.). After you decide what style you want to trade then look for resources to learn that. There are a ton of great groups to learn from as well. If you are interesting in trading cryptocurrencies or stocks, I have some blog posts and guides. For cryptocurrency specifically, I have to recommend Bitcoin Trading Challenge on YouTube and his Discord group. I am in there posting as well as a ton of good traders.

Practice…. Get into the charts and practice trade. Tradingview has a replay feature. Go to a historical price and start making practice trades after you learn some TA. Look at a LOT of charts. See what patterns are present before big moves. Constant study is needed. Good luck, if you have any questions I can help.
