I read on Historical First Trade Dates (mirror) the introduction dates of options on the E-mini S&P 500 Futures at the Chicago Mercantile Exchange (CME) :

  • E-mini options: 09/09/97
  • End-of-month Options on E-mini S&P 500: 05/21/06
  • Weekly Options on E-mini S&P 500:
    • Weeks 1 & 2: 8/24/09
    • Week 4: 7/06/10

When were EW3, the weekly Monday options (E1A,E2A,E3A,E4A,E5A) and the weekly Wednesday options (E1C,E2C,E3C,E4C,E5C) introduced?

Why do you care? In any case, you can easily Google the answer...

Effective Sunday, April 2, 2017 for trade date Monday, April 3, 2017, and pending all relevant CFTC regulatory review periods, Chicago Mercantile Exchange Inc. (“CME” or “Exchange”) will list Monday Weekly Options on the E-mini Standard and Poor’s Stock Price Index Futures and Standard and Poor’s 500 Stock Price Index Futures contracts (collectively the “Contracts”) for trading on CME Globex and for submission for clearing via CME ClearPort as described in Appendix A below. Appendix B below provides the Exchange fee schedule for the Contracts. source


The traditional E-mini S&P500 options (introduced on 09/09/97) already expire on the 3rd Friday, so there's no need for another "weekly" option that expires at the same time.

  • Thanks. Isn't the traditional E-mini S&P500 option quarterly? If so, how about the remaining the 3rd Friday of January, the 3rd Friday of February, the 3rd Friday of April, etc.? Commented Aug 22, 2017 at 23:59
