I don't know this information is true like 90/10 but there is a
Pareto Principle that if you apply for trading profit and loss probability in a trader community, you will have like 80% loss, 20% profit. It's not too far from 90% loss and 10% profit and the fact can be somewhere around 80% to90% loss, in the middle or lower than 80% or higher than 20% loss, but this fact about risk of trading is very strong warning on newbie traders.
You apparently haven't realised that this statistic is generally for traders, not day traders. The more often you trade, the more likely you are to lose money.
If they think trading is easy, this information is strong enough to wake newbie traders up from their unrealistic dream.
Do you want
to put your money where your mouth is?
In a period of 1 year? 5 years? I doubt anybody tried going back in 5 years to ask the same people if they managed to make profit.
I can almost guarantee in the longer period of tie the 10% in profit will become 1%.
Day trading puts you even more at risk.
It's just like that.
<...> you know what I mean.
Yes, it's clear to me that what you mean has more to do with writing whatever it takes to make up your weekly quota than with sharing knowledge you have on the subject.
