IV - A thread
In financial mathematics, implied volatility of an option contract is
that value of the volatility of the underlying instrument which, when
input in an option pricing model ) will return a theoretical value equal to the current market price of the option (1/n)
Implied volatility, a forward-looking and subjective measure, differs
from historical volatility because the latter is calculated from known
past returns of a security. .

To understand where Implied Volatility stands in terms of the underlying, implied volatility rank is used to understand its implied volatility from a one year high and low IV.

Options traders are always looking at the IV and IVR/IVP. For option
buyers, a low IV environment is best to initiate positions as the
subsequent rise in IV actually helps their positions . Even if the IV
remains flat, the position is not hurt by volatility (4/n)
Option sellers on the other hand are looking for high IV scenarios, where
the subsequent fall in IV ( known a vol crush , most often seen after
earnings/events) helps their positions. Here also, if the IV does not
rise, it does not hurt a seller's positions (5/n)
