FLEX Options

"Flexible Exchange Options" or "FLEX Options" are designed to extend investor access to customized derivative products. FLEX options combine the benefits of contract customization with the advantages of listing and can provide investors with:

  • The ability to customize key contract terms, like size, exercise price, exercise style and expiration date
  • Price discovery in competitive, transparent, auction markets
  • A secondary market to offset positions
  • Contract guarantee and virtual elimination of counter-party risk FLEX options combine the benefits of customization with the advantages of listing and are available on all option products listed on each NYSE options market

FLEX Trades are permissible on options classes not listed on the NYSE options markets but require certification with the OCC on the day before the FLEX trade is executed. Cut off time for certification by the exchange is 12:00 Noon ET. Therefore, all requests to trade FLEX options on non-American/Arca Options must be submitted before 11:30am on the day before the expected trade date.

To request an underlying to be qualified as FLEX eligible, submit a request to the relevant NYSE options markets:
