DEFINITION of 'International Securities Exchange - ISE'

An electronic options exchange that was launched in 2000. The exchange provides investors with greater liquidity and the ability to execute transactions at a much faster rate than the open-cry trading floor that has historically been the basis for options trading. In addition to being an options exchange, the ISE is also a publicly traded company.

BREAKING DOWN 'International Securities Exchange - ISE'
