"80%" it's very unlikely, say it is true, you just do the opposite and you have free money. I suspect the correct overall percentage should be much closer to 50%. Finding a profitable strategy should be much more difficult than "do the opposite of day traders", right?

What does "do the opposite of day traders" entail?

If it's to not trade daily then yes, having a profitable strategy is trivial: just buy index funds.

If you think it's possible to reliably trade better than day traders, you're probably just as deluded as them.

That being said, this data set is unlikely the be representative. The best traders are using something like IB, not eToro.

No, I was just pointing out that 80% is not very likely and is probably some sort of bias or mis-representation. In fact it would be a great compliment for them because they would be getting consistently the opposite of the market (If they overall lose money it must be that at least on the weighted average of their bets they get it wrong, maybe one big wrong and many little right ones, or mostly all moderately wrong, etc..).

it is at least partly because 100 % of day traders do less than 100 % of trades. And they play against people who are vastly more intelligent, better equipped, etc... on average. As a day trader, the odds are overwhelmingly against you.
