A trading strategy or play masterminded by a very ingenious trader in which the pray- usually another experienced traded- falls victim of an illusion that the price offered by the first trader is the best attractive and the moment to trade is optimal. However, after the trade the price usually moves (sometimes for a short period of time)in the opposite direction leading to disappointment and even despair.
