Linear Regression
Overview
Linear Regression is a statistical method for finding the “line of best fit”. Given a set of points, the Least Squares Method is used to calculate a line that best sums up the trend of the market.
To add the tool to your chart, select the tool from the Statistical tool group, and left-click on the bar on the chart you wish to calculate the tool from. Next, extend the lines and left-click again where you want it to end. Optuma will then draw the tool using the default settings.
Actions & Properties
Actions
Add Line Alert: Selecting this action will set a Line Alert based on the selected line.
Add to Toolbar: Adds the selected tool to your custom toolbar.
Apply Settings to All: When multiple Linear Regression 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 Linear Regression 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 Linear Regression to a chart, the tool will display using the new settings.
Delete: Deletes the tool from the chart.
