INVESTOPEDIA EXPLAINS 'Price Rate Of Change - ROC'

Many traders use a value greater than zero to indicate an increase in upward momentum and a value less than zero to indicate an increase in selling pressure. However, some of the most valuable signals are generated when the price of the asset and the ROC are heading in opposite directions (known as divergence). For example, in the chart above you can see that the ROC is sloping downward while the price of the asset is increasing. This is generally an early indication that a sharp decline may be on the way.
