The moving-average with a percentage price band system (MAPB system) belongs to a technical family derived from moving averages. Moving averages come in many forms-that is, simple moving averages, exponentially weighted, linearly weighted, and so on. The MAPB system employs a simple moving average with a band based on a percentage of price centered around it. A signal to initiate a position occurs whenever the closing price breaks outside the band. A signal to exit a position occurs when the price recrosses the moving average. The band creates a neutral zone in which the trader is neither long nor short. [See also DMAC]
