There are people who are so good in trading that they hardly experience loss while trading, and there are those who are still novice and lose money every time.
And how exactly do you know that there are people who hardly lose on their trades? Is it based on facts or just an assumption of yours? There are too many people online claiming to be an expert or elite trader.
If you look further, they mostly try to sell you signals or memberships to make a few bucks. What expert or elite trader needs these forms of income if trading is so profitable?
There is way too much shady business going on in this industry, all to make sure newbies who don't know shit about trading or investing will sign up and put all their faith and hope into someone's basic understanding of TA.
