Everyone makes profits and losses. No one, no theory is perfect.
Now back to the question, the one who manages EXITS in a trade are signs of successful trader. Exit comes after entry and that is where all the psychological game kicks off. No body enters without solid backing of theory and analysis (whatever may it be), if you do you are a gambler anyway, but exit is where psychology messes up with theory and analysis. Always stick to fundamentals, facts, analysis, and theory, don’t let emotions play with it. Yeah! believe in intuitions but only when you have experience, which comes after learning, and learning happens when you have faced every scenario.
“EXIT for sure”
P.S. I am newbie and have traded just for a month. Writing based on my one month of “small” experience.
