As an option writer, you would want to write options when volatility is high but generally, that is not the case as most of the time volatility is sticky at lower levels within a given regime.
Historical volatility has nothing to do with option prices as it is calculated purely using the underlying prices, but if the underlying prices become more volatile, it indicates a possible increase of volatility in the future.
This is the price you trade in the market, and you will be a price taker since the market as a whole is large.
Do note that the difference between IV and HV may not be a good indicator in cases of known events like results, monetary policies, fiscal policies and economic data releases.
The indicator will not be recent as the rolling number of days will act as a lag but still, the difference can provide indications if the underlying starts out-beating the market expectations and mostly in those cases, it tends to show a serial correlation.
