There's a distinct possibility a trader who experiences emotional issues, it's because they are attempting an endeavour which is beyond their skill. An easy trap to fall into is believing (falsely) in your own competence.
Now an incompetent trader is not necessarily an incompetent person, rather it means they are attempting something which is pure and simple beyond them.
This 'beyond them' could mean their computer systems, data, algos, trading experience and comprehension is no match for myriad of other professions they are competing against.
What I noticed was this thread is in the forex forum.
A heads up, I've been in this trading game for decades and would never contemplate trading forex, it's too damn difficult imo compared to how I trade stocks.
My opinion, those retail guys trading forex at home who think they can become consistently profitable are trying to climb a large waterfall. Your emotions will be constantly hammered with failure.
