Definition of International Securities Exchange (ISE):

1. The International Securities Exchange (ISE) is an electronic options exchange that was launched in 2000.

In addition to being an options exchange, the ISE is also a publicly traded company. In 2008, ISE became a wholly-owned subsidiary of the communications company Direct Edge, and in 2016, ISE became a wholly-owned subsidiary of Nasdaq.

2. The advent of the International Securities Exchange (ISE) was considered revolutionary. Computerized trading has proved extremely efficient, and has added to the liquidity in the options markets. This added liquidity has helped to reduce pricing volatility. Prior to electronic trading, investors looking to purchase or sell options relied solely on floor brokers to ■■■■■■■ their trades.
