In professional sports within the United States and Canada, a trade is a sports league transaction between sports clubs involving the exchange of player rights from one club/team to another. Though player rights are the primary trading assets, draft picks and/or cash are other assets that may be supplemented to consummate a trade, either packaged alongside player rights to be transferred to another team, or as standalone assets in exchange for player rights and/or draft picks in return. Typically, trades are completed between two clubs, but there are instances where trades are consummated between three or more clubs (e.g., a "three-way trade").
