I'll break it down very briefly ...
For this trade, I bought two SPX butterflies (for $85 each), sold one at 100% and let the other expire.
On the day, the SPX settled at 4704.81.
I was ...
Long 1 4715 put (+$1,019)
Short 2 4705 puts (-$38)
Long 1 4695 put ($0)
It all added up to a total of $981 profit on a trade that cost me just $170 total.
That precision -- and huge same-day profit potential -- is what makes 0DTE January so valuable to members.
