Should I Join a trading course for learning price action trading?

I wanted to learn more about how price action works sugggest a good course please

Good place to understand price action is to read books first.

If you can sit through with it, you will find tons of free youtube videos by doing research that will validate the ideas you have learned from the book.

Book 1 - https://amzn.to/3AGtjQl ( Trade Like a Stock Market Wizard: How to Achieve Super Performance in Stocks in Any Market)
Book 2 - https://amzn.to/3EVeOdQ ( Stan Weinstein’s Secrets For Profiting in Bull and Bear Markets )

A retail trader has no edge in intraday price action, Those claiming to make money make it off selling courses, i strongly belive they don;t work.

That is a very strong statement. There might be at least some on this forum who might disagree.

Agree with jacob, books and blogs ( even podcasts to get initial idea on who to follow) is a good way to begin.

Also, look at these free courses that actually have value instead of so many worthless paid courses designed only as an income source for seller using twitter marketing.

No course will turn you instantly profitable though. You need to learn and then apply to gain skills and then adapt to your market. That takes time - years probably.
I did not take these courses, only scanned them because i had already read his great book and free decade+ long blog. So if the approach looks good to you, then look at those too. Good luck
