The best way not to chase loses in trading is to see it as an alternative source of income, where you don't rely on it to take care of your responsibilities.
As soon as you see trading as a form of income, it is actually already too late and you will certainly lose (a lot of) money (unless you are a professional trader).
Trading should be seen for what it is: a form of entertainment like gambling in a casino.
Incidentally, the chances of success are quite similar, even good traders only achieve just over 50% successful trades.
