I've extended my program to show also the AM settled strikes:
T=SPX Calls(cED=54 cPM=3563 cAM=1551 cNS=0) Puts(cED=54 cPM=3563 cAM=1551 cNS=0)
As can be seen, today there are
54 ExpiryDates with 3563 PM Call strikes in total and 1551 AM Call strikes in total.
Same with Puts.
Sooo, in the above discussion
@stepandfetchit had posted such numbers from his database that go even beyond 20,000 Call strikes in total for both PM + AM.
I strongly believe that information by him cannot be true; he must have made an error, IMO,
most probably double-counted from SPX and SPXW together.
It's also impolite that he silently stopped answering questions.
If I make an error, then I surely admit it. We all are just humans, not machines...
