Footage of the trading floor at the Chicago Stock Exchange, i.e. NYSE Chicago, during the 1970s.

Begin with a long shot of downtown Chicago. With gusto, traders scream, jeer, curse, vent, and jockey for choice positions on the trading floor. One man uses the phone, looking worried, perhaps fearful that he's about to lose his client's money - or even his own life savings. Ticker tape signs run. People write in their handy notebooks. Several female traders look like they're about to have nervous breakdowns.
