When prices move up very rapidly, at some point the commodity is considered overbought; when they move down very rapidly, the commodity is considered oversold at some point. In either case, a reaction or reversal is imminent. The slope of the momentum oscillator is directly proportional to the velocity of the move, and the distance traveled up or down by this oscillator is proportional to the magnitude of the move.
