Thoughts on buying 0DTE straddles 30 min before close @SPX

Hi traders,

According to tastytrade research, selling 0DTE straddles 30 minutes before the close results in a 39% winrate with an average P&L of -190 USD for the straddle seller/writer. What are your thoughts on doing the exact opposite of selling: buy a 0DTE straddle 30min before the market close and letting it expire.

Seems to good to be true to me. You only risk the premium paid as a buyer for unlimited gains and get a high winrate as well. Am I missing something here?

TT did the study using "52 weeks worth of data".

Thanks!
