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
Trading is risky. Losing and winning is a part of it. If you/we cannot afford to lose then trading is for you/us. As a trader we must knew on the market will go through or we must knew how to raleade charts because if not we can make decision that might be a cause of losing money.
