You sounded like @destriero. Very advanced thinking.Very interesting. That's quite a project. Right now I'm working a strategy based on pinning and OI using flies to short the guts at the high OI. These are usually 2 to 4 day plays with a directional bias. I like longer DTE ones around earnings broken wing put side to collect a credit and have been using longer ones in VXX as a hedge. Am starting to explore some longer DTE set ups and will look to put one on this week.
Mine is simple, 121 is just a bet on the direction of the underlying.
