Quote from yip1997:
TorontoTrader suggested long calendars and you suggested short calendars. Can you two explain the reasons?
Will the day of the month (i.e. the beginning of the option month or close to expiration) make a difference in selecting the strategy?
It's a terrible proposition to buy long calendars if vol has peaked and dropping. It's long volatility and short gamma. Cutten qualified short volatility/long delta which are diametric-conditions for a long index calendar. Even a strike-pin [gamma-win] isn't likely to compensate for the loss to vol [delta loss, dV/dVol].
