many people have high IQ but not all of them are trading.
so, my question is "Whether high IQ it will affect the accuracy of one's decision making because to do Buy and Sell required the right decision-making, extensive analysis and detailed graph reading".
I do not think IQ is the decisive part. Winning or losing in each deal is based on analytical and emotional skills. I appreciate it if you keep your feelings. For those with high EQ they are often very sensitive to the market but if they can not keep their emotions, they lose even faster than those with low EQ.
