Overview

Rate of Change is used to display a measurement of the momentum of a security. High values indicate that the security is rapidly increasing in price, low values indicate the price is rapidly falling.

Calculation

The Rate of Change is calculated by subtracting the closing price n bars ago from today’s price. The value is then displayed as a percentage.

((Today's Close - Close 'n' bars ago)/Close 'n' bars ago) x 100

Actions

Actions

Copy Data to Clipboard: Will copy the tool’s values to the clipboard which can then be inserted into a spreadsheet, for example, allowing for further analysis.

Add to Toolbar: Adds the selected tool to your custom toolbar.

Apply Settings to All: When multiple Rate of Change tools have been applied to a chart, page or workbook, this action can be used to apply the settings of the one selected to other instances of the tool. This is a great time saver if an adjustment is made to the tool - such as line colour - as this allows all the other Rate of Change tools in the chart, page or entire workbook to be updated instantly.

Copy Tool: Allows you to copy the selected tool, which can then be pasted onto a different chart window.

Move to Back: If the tool is displaying in front of other tools or indicators clicking this action will move the tool view to the background.

Move to Front: If the tool is displaying behind other tools or indicators on the chart, clicking this action will bring the tool to the forefront.

Restore Default Settings: Click this action if you have adjusted the default settings of the tool, and wish to return to the standard properties originally installed with Optuma.

Save Settings as Default: If you have adjusted any of the tool’s properties (colour, for example) you can save the adjustments as your new default setting. Each time you apply a new Rate of Change to a chart, the tool will display using the new settings.

Delete: Deletes the tool from the chart.
