I have not seen a trader that do not lose sometimes, i may be new to the forum but been learning before now. it has nothing to do with sentiments but traders have to learn to accept trades the way it is, without attributing loss to any factors; as it leads to more rekts.
Always accept the market as it is without blaming any factors.
Always dyor too
I sperated traders by three. No matter how much earn you experience on day or short term, you have to lose sometimes. As my research long term with enough money, you don't need to lose anytime.
