Show Plot

Overview


The Show Plot tool displays as an indicator using the same scale as the price chart, calculated using a specified formula. For example, the red line in the image below plots the 52 week high price using the following formula:

HIGHESTHIGH(BARS=52, BACKTYPE=Weeks, INCBAR=True)

To add a Show Plot to your chart, select the tool from the Price tool group, and click on the chart to add the tool. Optuma will then draw the Show Plot on your chart using the default settings.

Saving the Script as an Indicator

It's possible to save the script as an indicator and add it to your toolbox. In the Script Editor window tick the Use as an Indicator box to be applied to the SameTool View.

You can then apply the tool from your toolbox and change the properties (colours, line width, etc) and Save Settings as Default under Actions, or add it to your toolbar as a custom button.

Actions & Properties


Actions


Add to Toolbar: Click this action to add the selected Show Plot to your custom toolbar.

Apply to All: This option expands to display the following:
  • Current Chart - If you have more than one occurrence of the tool applied to your chart, selecting this option will apply the properties of the current selection to the other tools.
  • Current Page - If you have more than one chart on the current page and the Show Plot is applied on each, then this option will transfer the currently selected property settings to each tool.
  • Current Workbook - For each chart that has the Show Plot tool applied, this option will transfer the selected tool's property settings to each tool on every chart in your workbook.

Copy Tool: Allows you to copy the selected Show Plot formula, that can then be pasted onto a different chart window.

Move to Back: This option allows the selected item to be positioned behind the chart.

Move to Front: This option allows the selected item to be positioned in front of the chart.

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