Usage of the Accelerator/Decelerator Indicator
The Accelerator/Decelerator Indicator measures the acceleration of the factors that cause the price changes. Therefore it outstrips the price, and it is a good anticipatory sign. If the acceleration decreases, it is very likely that the price will move in the opposite direction. Crossing the zero level is not a signal to open a position, however, the color change can be used as a sign.
In a strategy, the simplest way to use the indicator is to open a buy position if the indicator is above the zero level and changes its color, and to open a sell position if the indicator changes its color below the zero level.
