The essence why we trade is to make profit through taking and in trading the outcome we get is either lost or gain, but some people have taking trading to make profits as a do or die affairs, if they don't get exactly the profits they want, they would want to continue to get what they have targeted as profits. A mindset like this can lead to emotional feelings which can never be helpful to trading , people should learn to accept their lose and learn more to know what could be the cause for their failure in trading to get profits, than just trading continuously in lose without getting a good knowledge for better outcomes.
We all trade for profits, that some traders resort into trading with high emotions and when they fail in their trades, they easily become frustrated and eventually lost their concentration in trading. And it’s like a do or die thing like you said. However, I also believe that this can’t be avoided most especially for beginner traders as they tend to be highly emotional at first, but when they start learning some lessons in trading, that’s when they get wiser and become cautious when trading.
with high emotionality in trading, it can damage their common sense, so they cannot carry out strategies according to plan, I think emotion is the highest science in trading, because only we ourselves can fight it, so it is difficult to do or learn without doing it. practice in real. after that we will have our own feelings about trading, so we will feel every time the next movement will occur, and this can be obtained along with our experience of trading
It's true as you said, only from experience can we learn about controlling emotions in trading.
Before I started trading, I used to learn a lot of the science of controlling my emotions in theory but in reality it didn't work and as time went by I learned and understood valuable lessons in self-control for anything that would damage my thought patterns which would lead to emotions that were detrimental to myself Alone.
It's not only emotions that can be detrimental in trading, but also greed in taking profits that we do outside of the strategy, it will also disturb emotions which can end up being detrimental.
