Some lose money while some loses more while chasing their lost money it is better to let go off these loses and move forward in order to become a successful trader.
to be a successful trader is not a joke , need a powerful trading knowledge including a reliable support from a credible trading broker.
i think there is no way to become emotionless , because its a very common human nature . but we can control it by trading discipline and practice.
practice is important , there is no way to ignore . but the demo account of practice session actually not works.
generally, traders take demo account for practicing but this level does not work actually , for practice in a proper way i think live account best even though it is a little bit expensive.
yes , demo is okay , right now i am trading all exotic pairs in demo to see the performance how it works.
I think this happens because many do not analyze their mistakes and do not find their causes in order to adjust and improve their trading strategy and not make the same type of mistakes next time. They just continue trading with the same poor strategy and step on the same rake again.
