"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:

Equity FLEX

With Equity FLEX options, investors are able to set key contract terms like exercise prices, exercise styles, and expiration dates, and to trade in size, with no position or exercise limits. Equity FLEX options are traded on all listed options, including but not limited to, Stock Options, American Depository Receipts (ADRs) and exchange traded funds (ETFs).

A minimum 1 contract is required to open a new Equity Flex Option Series. For closing transactions the minimum is also 1 contract.

Index FLEX

Index-FLEX options may be traded on any multiply listed index upon which options trade.

A minimum 1 contract is required to open a new Index Flex Option Series.

Cash-Settled FLEX

Available only on NYSE American Options

For select eligible issues, the Exchange offers settlement style ‘cash’ (physical) as a Flexible term. To qualify, the underlying security must have an average daily notional value of $500 million or more and a national average daily volume of at least 4,680,000 shares (measured over the prior 6-month period each calendar year). If an underlying ETF ceases to satisfy the criteria, any new position overlying the ETF will only settle by physical delivery, and any open cash-settled FLEX ETF Option positions may be traded only to close the position.

Current Cash-Settled FLEX ETF Options Eligible Issues can be found here. Additional details can be found here.
