Surely you jest Why on earth would you sell a 1 Delta option,60 DTE?? How many of those bad boys fo you sell relative to your notional??
Strategy is backtested with my own software.. feb/march 2020 were my best months. I monitor the greeks constantly...
Different ways. Write high delta calls when vola is high. Buy put calendars when vola is low, have a long put spread above the written puts, sometimes convert written puts to written calls , etc.....
I don't write one SPX options, i have hundreds written puts at the moment... Total delta is most of the time negative...
Shorting something close to ATM on the call side? Out to Dec (example)? Any calendar (Dec/Jan) above 4500 is going to exceed your written prem. That doesn't make sense. Your hedge becomes the primary risk.
