I'm trying to find the meaning and origin of the term "jitney box". I know what a jitney is, and I recall reading in some investment/stock market context the term "jitney box". I have a general idea of its meaning but I have no idea where or how it originated. I've heard that it may have an Asian connection, but I'm not sure of this. I have searched several dictionaries and other references and have come up dry. Anybody?
