I know having no or almost no losing days in daytrading is possible.
You need a very good system, a small account, at least a few trades each day, and a double system.
I personally trade a double system. That means I daytrade a system to take the big waves, and a second system that is only used after a losing trade to recover quickly the loss in smaller trades . I have very close stops, and each time I get stopped out (which almost never happens as I get out before the stop is reached), I recover from that loss in 1 or maximum 2 trades. It is necessary to do a few trades per day, if not you end up with a losing day as you cannot recover the loss.
So normally I stay each day positive. Positive means above zero but can also be a big profit.
I noticed also that I give normally back less than 10% of my profits in losing trades.
10 years ago I would not have believed that this is possible. But I understand now the markets much better.
So I believe
@nooby_mcnoob , or at least believe that it is possible. But only for the happy few.
Top tier HFT firms cannot work in that way as it is limited in size and also needs a lot of focus just on the ES. These HFT firms automate things and cannot focus on each item like we focus on the ES. The work with a kind of "mass product". Trading billions comes at a cost, they cannot work "artisanal" so they lose a lot of "efficiency".
