I tested a very plain boring wheel, as follows:
1) Sell a covered OTM call at 1 month maturity with 30% probability of getting in the money (so this means also buy 100 shares of stock).
2) If the stock stays below the call strike at option maturity, goto #1, else goto 3.
3) Sell a cash covered OTM put at 1 month to maturity with 30% probability of getting in the money (so a naked put).
4) If the stock stays above the put strike at option maturity, goto #3, else goto 1.
I guess with tweaks it would fare better. My strategy is the result of years of experiments, chances of falling upon it from the first attempt are non-existing. Particularly you see that it's able to extract profitability from a market that is otherwise losing either on long stock or wheel strategy (XME). Gotta tell you it wasn't an easy feat to achieve.
