Does anyone know where I can find the 'official' RTH Open price for the day? I tried the CME website but could only find the full session open. Thanks!
Go to Time and Sales and look at the first print with a 08:30:00 CST time stamp. For 12/17/2010 the first print for ES at 08:30:00 CST was 1237.50 with a volume of 338.
