The Hollywood Stock Exchange is tentatively set to launch as a real-money commodity exchange April 20.

A spokesman said the exchange is “on track” to begin listing films’ boxoffice projections for live trading from that date. HSX filed with the U.S. Commodity Futures Trading Commission for approval as an active trading site in November 2008 and recently entered the final phase of regulatory review.

Since 1998, HSX has allowed just-for-fun traders to buy and sell valueless shares in Hollywood films based on forecasts of what the pics will ring up. Once launched, a new HSX site will list current and imminent movie releases with their projected four-week domestic grosses and allow exchange users to take long or short positions on the films.

A formal announcement about rules and guidelines for HSX users is expected closer to the launch. The exchange hopes to lure hobbyist investors as well as industry professionals, though the latter will be prohibited from improper insider activity.
