These people are gambling and these comments are full of survivorship bias. Just passive invest, don't try to time it.

This article is mostly about options trading. If you take a basic options course and learn about greeks, some of it will start to make sense. Tasty Trade and TD Ameritrade offer free courses, though you might need to open an account for the latter.

Just in case anyone thinks of signing up for TDA, they have terrible software and they are also being merged into Schwab soon. I would look elsewhere.

Tasty trade can teach you a lot of the basics... Start slow (please) with money you're prepared to lose

You mean like investopedia?
