Schema: OptionPrintSet (ID: 2815)
OptionPrintSet records contain every option print along with quote, surface, and SR probability details at print time. These records also contain T+1M and T+10M forward mark details. These records are created for every print at the time of print and are published to the SpiderRock elastic cluster 10 minutes later when T + 10M forward marks are available.
