Flex option

An exchange-traded option that allows the holder to determine the quantity or amount of the underlying, the basis of exercise, the exercise price and maturity, so that the terms of the option are customized rather than standardized as is generally the case.

The word "flex" was formed from the first two letters of the words FLexible and EXchange.
