http://www.cboe.com/data/historical-options-data/index-settlement-values The symbol on your platfrom should be "SET" when updated but I would wait for confirmation. Right now SET is 2809.92
Thank you. In the case of ES futures, do they round it to 2812 for settlement or do you get the fraction?
That was the settlement price for SPX options. ES might have another process. https://www.cmegroup.com/confluence/display/EPICSANDBOX/Standard+and+Poors+500+Futures
