For option traders, market volatility is very important, but please note that the so-called option volatility actually has nothing to do with the price of the option, but reflects the price change of the option against the underlying asset. The realized volatility is the standard deviation of the price fluctuation range of the underlying asset in the past period of time calculated by the variance formula, and the implied volatility is the result calculated by the BS formula. Implied volatility measures market expectations of future volatility. An increase in implied volatility means a corresponding increase in the time value of the option, and vice versa means a decrease in the time value. In other words, if the volatility can be predicted more accurately, then you only need to buy when the volatility is high and sell when the volatility is low, and you can achieve better returns.
