Sam Seiden -used to be with Online Trading Academy https://www.tradingschools.org/pinnacle-institute-of-trading-and-investing-review/
I don't know what Sam is doing nowadays, but when he was with Online Trading Academy, I learned his method, and I have been using it ever since. It works for me. I only trade daily bars of ETFs, and I have more than doubled my trading account in 2019 as well as 2020. 2021 is profitable this year, but it's running at less than 100% so far. I don't know why the author of the article is so angry with Sam. I am happy with the results from Sam's method.
