I think the idea with selling otm premium (and thus generally putting the probability of expiring out of the money always in your theoretical favor), is simply to allow people to live long enough to figure something out. They've surely seen new accounts dying spectacular deaths by buying OTM premium, so their mantra is essentially trying to keep newbies alive and give them a fighting chance.
I think if you stick to their basic rules (I paraphrase here, could be mistaken, happy to have Tom or Bat correct me), your account may live awhile:
1. Sell otm (pref delta ~ .3) options - cash secured or as a credit spread(s) - 50-30 days out
2. Stay small (they don't specify but I would be concerned about risking more than a few % per trade in normal circumstances, certainly no more than 10% cash should a naked underlying position have a serious black swan scenario and go to zero, or double in the case of short calls)
3. Make sure IV rank is > 50% (basically higher than 50% of the measured IVs for the last 365 days for you none TOS/TT people)
4. Make sure both the underlying and the options are liquid (personally I only care that the underlying is very liquid for short naked positions but your mileage may vary, certainly any spread or anything you plan to exit before expiration needs to have liquid options).
5. Ideally have your portfolio as a whole close delta-neutral (essentially a long/short strategy so that it is insulated from broad price shocks, in theory...)
Is there an edge in there just from the above? Hmmm not so sure, probably some edge in SPX as we know there is a put premium in there that "seems" to be generally mis-priced since 1987 (not a coincidence I suspect...). For instruments as a whole, I wouldn't bet that just the above is going to bring home the bacon.
However, if you add some additional criteria that gives you a directional edge and is of a nature than generates a lot of scratches and small gains/small losers, with very little outliers on either side, then you have something where the above could be more useful/profitable than simply going long/short the underlying...
Yes, there is an edge there and that is a profitable long term strategy, fact. I know option traders as a whole like to pretend there's some merit to being as complicated as humanly possible (myself included) the truth is sticking to very simple trade rules like the ones above taken from TT actually do work, to the tune of about 7-10% a year on average.
It works, period. So criticizing Tasty Trade for something that is quantifiably true seems silly to me. Now if the guys on Tasty Trade ever claim that those trade rules could yield higher than 10% a year, then I'd take issue with it. But as long as they are stating realistic expectations of 7-10%, then they are absolutely correct.
The problem is, VERY few people have the trading discipline to follow such simple and easy trading rules month after month, year after year, decade after decade.
