Question: why the american style ES futures option is not listed at

Discussion in 'Trading' started by archer001, May 25, 2007.

  1. At, the european style EOM options on ES is listed under its product description page.

    However, I know for sure there are american style options on ES. I can find the quotes in CME's own daily bulletin, and I can trade it via IB.

    Then what is the reason CME do not describe this product at its website?
  2. anybody help?
