Simple option idea.
Write 1 0DTE SPX straddle closest to the money, at market open and then every 30 minutes thereafter until 30 minutes before market close. For a total of 13 straddles.
Then take assignment or expiration of all 13 straddles.
How do I see the daily results of how this performed over the last year?
Or how much to pay someone to generate this data correctly?
