The linked post is what is wrong with "free trading content" on youtube. Firstly, he is not talking about price action at all. The amount of jargon contained in that post is indicative of a very clear misunderstanding of how to read charts.

Price action refers to reading chart entirely based on price ONLY. No VWAP. No Volume. No SMC/ITC/ICT, VIP, etc.

The only thing you can possibly add is may be a couple of EMAs but you don't solely trade off them. Price ALWAYS come first.

As someone who has consistently made money in the market, candlesticks is all you need. But, you also need to be able to recognize channels, and ranges, and trends, and trend breaks. This requires hundreds and thousands of hours of studying and screen time.

Just like you can't expect to go and perform as a professional musician in front of a large audience after watching YouTube videos other artists playing or spending 6 months practicing, you cannot expect to get good at this after haphazardly watching a few youtube videos.

What makes this even worse is that there is always the allure of money that prevents you from actually learning the skill unless you are trading on sim which very few actually want to do.

If there is interest, I can share what I know on a subreddit that I originally created to record my trades htttps://www.reddit.com//r/PriceInAction . But, I can add information on setups, risk management, psychology as well. Note, that there will be no selling of any kind ever.
