The Ferengi Futures Exchange was a center of Ferengi commerce on Ferenginar. Unlike the Ferengi Market Exchange, the Futures Exchange did not deal in established companies but instead allowed Ferengi or other investors to gamble on the future price of commodities such as latinum and duranium.
Vacuum desiccated remains of famous Ferengi could be sold as collectibles on the exchange. In 2372, Quark, after being misdiagnosed with Dorek Syndrome, auctioned his own remains on the Exchange and Brunt purchased the entire collection for five hundred bars of latinum. (DS9: "Body Parts")
One year later, Quark realized that the mental faculties of Grand Nagus Zek had begun to deteriorate when he failed to accurately calculate a seventeen percent increase in the price of duranium on the Exchange. (DS9: "Ferengi Love Songs")
