Success depends mainly or even almost for 100% from the qualifications of the trader.
If you have the qualifications to be a daytrader you should daytrade.
If you only have the qualifications to be an investor, you should just invest.
No investor can ever beat the returns of a good daytrader.
"Silly" is to do something without having the needed qualidications. But even investors can do silly things. Silly depends on the person who is doing something, it depends not on what product he is trading.
How much of a day traders returns are based on leverage? How much is based on different accounting?
You lost 100percent of your account. That wasn’t really 100percent then if you had money on the sidelines.
if you took 100percent of your liquid assets (what a typical investor would employ) and didn’t have more notional than your account, what would your returns be?
