It's not that there are traders who don't record losses at all. This isn't possible because profit and loss are an integral part of trading.
Even the best legacy traders in the world don't always end up closing a profitable position, and that while people here say that the stock market is easy to trade on, which obviously isn't the case.
To surpass this hurdle of always losing a trade, one needs to constantly oil one's trading skills.
You can't always lose with trading, not even if you blindly buy and sell at a random price. The luck factor that plays a role will make you profit from certain trades even if they don't make sense, that's just how it works.
In the long run you'll either end up with a big bag of profit or with severe losses, but not to the degree where you lose everything at once, unless you go all in on a single trade and you get liquidated in the process.
