I noticed that far out of money options can have insane spreads. While I am writing this (market closed): RUT Oct 31C 1720 has 9.0 ask and 0 bid. RUT Nov 2C 1715 has 0.65 ask and 0.25 bid. It will change once the market is open but the price swing was massive. Who the hell makes these prices? What makes back option so much more volatile?
