FLEXIBLE EXCHANGE (FLEX) OPTION Definition & Legal Meaning

Definition & Citations:

A standardized OPTION contract traded on an EXCHANGE that allows buyers and sellers to select key contract features such as STRIKE PRICE, EXERCISE style, and maturity date. Though not as bespoke as an OVERTHECOUNTER (OTC) OPTION, the flex structure provides a degree of customization that allows it to compete with certain OTC contracts.
