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
What you have to understand is that the changes that occur in the market are certainly a cause, indeed all traders do not have the right to blame anyone in this case, but they also must be observant and careful in dealing with the market situation at all times.
