The Momentum indicator tracks the velocity or speed of a price move, whether it be up or down.

It is a very useful indicator and is calculated by subtracting the latest price from the price, (x) intervals ago.

The formula for calculating the Momentum level for a particular interval is as follows:


The resulting amount is plotted in its own indicator window below the price chart.

As the figure is either positive or negative, it oscillates above and below zero level on the y-axis.

This indicator can be effectively displayed as a line, histogram or step.

User Settings


The user can select the previous interval whose closing price will be using in the Momentum calculation.

Type in a whole number representing the number of previous intervals in the Periods text box in the Parameters tab of the Momentum Properties dialog box. The graph will be recalculated and displayed using the new interval date for all of the levels.

The default number of periods is 20, this setting can be changed and saved using the Default button.

Data Field

The Close data field is the default data field used to calculate Momentum. Most technical analysts consider Close to be the most significant price of any interval. However, there are reasons why a different data field should be selected.

Users can choose from the following data fields in the drop-down list: Open, High, Low, Close, Bid, Ask or Open Interest.


The Style selected for the plot can be one of the following: Solid, Dashes, Dots, Points, Histogram or Step.

The plot can be set to be displayed inverted. When this setting is turned on, a small Inv icon will appear in the Volume Momentum's scale (Y-axis).

Once the style is selected the Color, Weighting and Visibility can also be controlled from this page.

The Scale's display is controlled from the Scale Settings and Scale Appearance tabbed pages.
