Thank you in advance for answering. 1) Are DITM options controlled by MM's? Does there exist a purely electronic market where I can purchase a DITM option at the price quoted at the ask and be assured a quick fill? 2) Concerning the "6 levels of risk" of an option, what is the sixth called? I know Vega, Delta, Gamma, Theta and Rho -- what is the sixth? Is this the Gamma of Gamma -- and is this important for people like Metooxx? 3) Is the VEGA of an option always greatest for ATM options? How does VEGA change in response to price movement of the underlying? 4) If a stock suddenly falls (THC) with a much greater than three standard deviation movement, will VEGA be greater for PUTS than CALLS? 5) When volatility is factored into options, why isn't the same formula used for all classes of a specific option (i.e. QQQ). Why are there discrepancies in THETA and VEGA? If a model is designed to model the underlying's price movements, how come all the options on a certain time series do not follow that model? 6) Is Gamma merely the second derivative of the black-sholes model? 7) Do any option models take into account the volatility of volatility? Thanks in advance!
