Everyday? No, I think that would be absolutely impossible. I think every year is extraordinarily hard (over say 10+ years), let alone every month, week, or day.
If you a profitable scalper, you should absolutely be profitable every month given the high volume of trades. If you take 500 60/40 trades in a month, it is mathematically improbable for you to have a losing month.
The logic is less so for a daytrader who averages only 50 trades per month, but still unlikely to have a losing month.
For swing traders and buy-and-hold investors obviously you can have a losing month due to variance from small number of trades.
