Zero Degree Angles

Overview


The main concept that needs to be understood when using a Gann Fan is the relationship between time and price that Gann proposed. This means that for one unit of time the market will rise (or fall) by one unit of price, resulting in a one-by-one line (1 x 1). The Zero Degrees Angle tool uses this same principle, however, there are two main differences: when the angle lines hit the zero price level a vertical line is drawn on the chart, along with a reversed angle line. The resulting lines can be used to help identify potential turning points and support/resistance levels in the market.



To add the tool to your chart, select the tool from the Gann tool group, and left-click on the bar on the chart you wish to calculate the tool from. Optuma will then draw the tool using the default settings.

Actions & Properties


Actions


Add New Level: Select this action to add a new level to the tool.

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

Apply Settings to All: When multiple Zero Degree Angles 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 Zero Degree Angles 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 Zero Degree Angles to a chart, the tool will display using the new settings.

Delete: Deletes the tool from the chart.

Properties


Tool Name: Allows for the name of the tool to be changed, as displayed in the Structure Panel.

Gann Levels: Click on this option to display the different Gann Fan Angle levels.
To add a new level to the chart, left-click on the blue + button and enter the values as needed.
  • Value - Sets the time/price ratio for the angle (e.g. 1 x 2). To change the value amount, click in the field and enter the new value.
  • Line Style - Sets the line type, thickness, colour and transparency of the angle lines.
  • Visible - To hide a level, deselect the check box with the green tick.

Base Line Style:
Allows you to adjust the style, width, colour and visibility of the base line.

Use Chart's Price Unit: By default, the price unit of the chart is used in the tool calculation. Untick the box to manually adjust the value in the Price Unit property.

Price Unit: This option is available when the Use Chart's Price Unit box is unticked (see above). The value in this field determines what one unit of price is equal to in the tool's calculation. This may require adjustment depending on the data file and timeframe that the Gann tool is applied to. To change the value, simply click in the field and enter a new value.

Show Label: Check this box to display the line values.

Font Size:
If Show Label is selected you can adjust the size of the text displayed for the label. Moving the slider bar to the right increases the font size.

Zero Level: The level can set to use the zero price or the all time low. Update: From Optuma v1.6 and later the Zero Level property can now support a custom level for the angles to plot from. In the following example the Zero Level has been set to 500.



You can see as the levels hit the $500 price mark the angles are reflected.

Tool Transparency: Use this slider bar to adjust the transparency of the tool. Moving the slider to the left will increase the transparency of the tool.

Visible: Un-tick this checkbox to hide the tool from the chart.
