I agree with ever word you said. I think it was ICT trader who once said something like this: "Having mental stop losses is a sure way to go mental". And yes, cutting emotions entirely is essential. People who can't do that, have no business being in trading at all.
Its a big challenge for us as a gambler, we know losing will come to us at any moment. Anticipation into such thing will be the best solution we can do before it becomes worst. If we still have a presence in our mind, we can make it right. Losing our emotions will be our enemy all the time especially when stress goes out. Tried to stay calm and wisely think what we have to do next.
