like an idiot I forgot to close my SPX spread yesterday. I wonder why no one has thought of creating a software program to find the SPX stock that have not traded and then just executing a single share for all of them
Then they wonder why no one has though of creating a software program to remind traders Not to forget closing their SPX options just before expiring!
I too wonder why at least one of the thousands of traders holding SPX don't find it in their best interest to trade 1 share of every stock that hasn't trades 30 seconds (or some other arbitrary number) after the open. Some days it goes on for literally hours. There's got to be an opportunity there somewhere.
