Cross Correlation

Overview


An Analyst is often interested in whether one security leads or lags another security. We can use Cross Correlation to achieve this. The process is very similar to Auto Correlation (looking for correlation offsets within the one security) but Cross Correlation repeats the correlation process on ever increasing offsets of a second security. The result is a plot which shows all the correlation values from lagging through to leading.


To add the tool to your chart, select the tool from the Statistical tool group, and left-click on the chart to add the tool. Optuma will then draw the tool in a window below the chart using the default settings.

Scripting Function: CCF()

Actions & Properties


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 Cross Correlation 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 Cross Correlation 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 Cross Correlation to a chart, the tool will display using the new settings.

Delete: Deletes the tool from the chart.
