Older study but good data. They keep showing 45 DTE is always the best performance for selling options OTM. Also managing at 50% seems to be key to consistent gains.

I like the #pietrades a lot and will continue to do them as my primary trade tactic but for those with bigger accounts may be better to sell 45 DTE and set up ladders. Can stay farther OTM, stay on the sweet spot of decay fro OTM options, less adjusting, and steady income. This alludes to the million dollar account with SPY from a few days ago.
