Hallo Wilmott Community,
I would like to find closing prices for all options written on S&P 500. I tried OptionMetrics from Wharton School but unfortunately you only find bid and ask prices.
Is there any other database you can recommend which offer closing prices as is without extra programming work? It would be very helpful. Thanks a lot for any information.
I am not only looking fir todays prices, I am more interested in historical closing prices.
