Trade has been judicially defined as follows:
In May v. Sloan, it is said that “the word ‘trade’ in its broadest signification, includes not only the business of exchanging commodities by barter, but the business of buying and selling for money or commerce and traffic generally."
In Queen Insurance Company v. State, trade is defined as, “the word 'trade' means traffic, which is defined to be the passing of goods and commodities from one person to another for an equivalent in goods or money."
In re Grand Jury, trade is defined as “the exchange of commodities for other commodities or for money; the business of buying and selling; dealing by way of sale or exchange." United States v. Douglas, 190 F. 482 (8th Cir. S.D. 1911)
