While having a high IQ can certainly be an advantage in many areas of life, it is not strictly necessary for successful option trading. While some aspects of option trading, such as quantitative analysis, may require advanced mathematical skills, there are many successful traders who do not have exceptionally high IQs.
What is more important for success in option trading is a combination of knowledge, experience, and discipline. Successful traders typically have a deep understanding of market conditions, a keen sense of timing, and the ability to manage risk effectively. They also have the discipline to stick to their trading plans and not let emotions cloud their judgment.
That being said, having a high IQ can certainly be an advantage in certain aspects of option trading, such as developing and testing new trading strategies, understanding complex financial models, and quickly adapting to changing market conditions. However, it is not a prerequisite for success, and traders with lower IQs can still be highly successful if they have the right combination of skills and traits.
