Somebody has to sell you that spread. If it's systemically unprofitable for them, which it must by if it's systemically profitable for you, they're going to stop selling it. So there is no magic combination of options that will consistently be profitable for you over a long period of time. There may be a corner of the options world where options are mispriced, that's what we're all on the lookout for. But it's probably not going to be through the way you combine ever more complicated groups of options.
That's a problematically narrow view of the options market.
In classic Price Theory, the foundational idea is that "we can't say" what good or profit or service will come from one expenditure over another, BUT WE DON'T NEED TO, as all of that value is captured in the price a willing buyer would buy, or a willing seller would sell.
If someone wishes to construct a far-OTM *spread*, can we say whether their purchase or sale of any particular strike is dumb? Smart? Perceptive? Mis-priced?? Not our business. Our job is to assess the risk to OUR OWN capital put up for margin, put in an appropriate order, and have at it.
I'm not in the business of selling an over-priced option to dumb buyers; nor do I *think*of* myself as a sucker for buying an over-priced option myself. I'm just a guy accepting a little pawned-off risk from someone else (who feels they have too much).
