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".
Engaging into trading depends on the person himself. Higher IQ I think, has a little impact on one's success. Ofcouse, having higher IQ means a person would have a better decision making skills especially whenever the market is falling due to the nature of market volatility. So those that are having high IQ are more likely to avoid loss of profit due to their actions during the downfall in their investment as well as situation in the market.
High IQ together with a good self control and discipline would be always a good team-up for a trader because high IQ would be still useless if you cant able to control your temper or emotions which it would definitely lead to loss in your trading career but i do agree into the point that having higher IQ would always have the advantage rather than on the average ones but though it would be still needed on how you would utilize that given gift into you.
