Ok, any link or read/write-up you can advise please ? There is so many here, so a selection would be useful.
The TA traders you watch are in the business to sell more videos, not to trade for living - they are all mediocre, at best, educators. Charting is useless, but some TA indicators are used as features in machine learning models.
What is TA? Once you find the definition and if market condition is not included then add it. If money management is not included, then add that too. That should erase the BS.
