Bucket shop (stock market)

A bucket shop is a business that allows gambling based on the prices of stocks or commodities. A 1906 U.S. Supreme Court ruling defined a bucket shop as "an establishment, nominally for the transaction of a stock exchange business, or business of similar character, but really for the registration of bets, or wagers, usually for small amounts, on the rise or fall of the prices of stocks, grain, oil, etc., there being no transfer or delivery of the stock or commodities nominally dealt in".
