Ferengi Futures Exchange

From Memory Alpha, the free Star Trek reference

The Ferengi Futures Exchange is a center of Ferengi commerce on Ferenginar. Unlike the Ferengi Market Exchange, the Futures Exchange does not deal in established companies but instead allows 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 where Brunt purchased the entire collection for 500 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 17 percent increase in the price of duranium on the Exchange. (DS9: "Ferengi Love Songs")
