Open interest is the total number of contracts that have not yet been offset or taken to delivery.

OneChicago President Marty Doyle said, “Our latest open interest record reflects the confidence market participants have in OneChicago. And the Exchange’s volume increases are the result of more and more traders using single stock futures for a variety of their portfolio needs.”

Each single stock futures contract is equivalent to 100 shares of the underlying stock or exchange-traded fund.

The Exchange lists 169 futures on single stocks, including futures on the DIAMONDS® Trust. An additional eleven new single stock futures contracts begin trading July 8.
