• JAMMING
  
  Definition: Executing a large sell (buy) order in stages by asking for a market on a small size, hitting the bid (offer), then repeating the process with a different market maker, ultimately driving the price considerably lower (higher). Application: "It is entirely against proper market etiquette in foreign exchange and gold, but somewhat permissible in fixed income trading. You never jam a friend." (Nassim Taleb)
