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".
IQ is greatly affecting all the things that person is doing in whole life in every sphere of it. So in my humble opinion intellect quality is defining how successful you will be whatever you are going to do.
