reverse iron butterfly on spx 0dte

many trigger words in the title but let's go with it. came across this strategy from a guy in the quantum options fb group. the idea is to find a price you DONT think spx will close and buy two debit spread 5 points wide (put + call) paying a maximum of $4.5 per entry. Defined risk and reward of 9:1 You always enter with a limit price so slippage should not be an issue Pin risk does exist The original author posted Option Omega backtests which were pretty successful After downloading spx daily data I found out that spx moves on average 35 points. This structure spans 10 points with 1 specific price causing the max loss. I like this idea because you are not strictly predicting direction and can possibly be combined with regime based filters, prev close, possibly order flow to find a good candidate for the strike price . Anyone that has used this strategy and can share their experience?
