Acceleration

An acceleration study identifies the rate of change in momentum.

A momentum study indicates the rate at which prices change; an acceleration study indicates the rate of change in momentum. When an acceleration study yields a positive value, prices are not only rising, they are also rising at a faster rate. Conversely, when an acceleration study yields a negative value, prices are falling at a faster rate.

Formula:

Where:

ACC = current acceleration value

MOMt = current momentum value

MOMt-n = momentum value n periods ago
