Research or backrests on iron butterflies?

Specifically, I’m looking for selling one ATM on SPY, MOO, daily.

 

Btw, typo in the he’d. I meant backtest, if it wasn’t obvious.

 

What days to expiration and deltas are you thinking?

DTR had this as one of their best set ups for a SPX iron condor:

1. Profit Factor (4.5%):
   • 80 DTE
   • ST structure
   • 25 pt. wings
   • 8 delta shorts
   • 300% stop loss / 50% profit taking
   • • 2007 - 2016 win rate: 96%
     • 2016 - 2017 win rate: 83%

I am sure there are differences in how these were implemented.
Here's my test:


I see an 80% win rate.

Here are some trade examples:



Let me know if I did this correctly.

Nowadays you have options that expire every (working) day, so surely this is possible on some indexes.

 

Wow. Thanks. Give me time to peruse.
