BREAKING DOWN 'Cincinnati Stock Exchange - CSE'
In 1980, the CSE replaced its physical trading floor with a much more efficient geographically dispersed electronic trading floor because of amendments made in 1975 to the Securities and Exchange Act. In 1986, the CSE became the first fully electronic exchange in the United States, capable of automatically executing orders through the Intermarket Trading System. The CSE was also the first exchange to introduce a competing specialist system, in 1992.
