Dynamic Gann Fan 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). Unlike the standard Gann Fan tool which draws the angles based on the selected Price Unit (eg 0.1, 1, 10), the Dynamic Gann Fan Angle tool allows the user to control the 1 x 1 line between two points, thus calculating the Price Unit of the move.

In this example below, the 1 x 1 line has been placed between Microsoft's low and the high, a difference of 32.35 in 163 trading days (bars on a daily chart). This means that the price unit of the Gann Fan is 0.1985 (32.35 / 163); in other words, MSFT moved up an average of 0.1985 points per day between those two points.

Note: to make the 1 x 1 line a geometric 45 degrees, lock the Time/Price Ratio in the bottom-right corner to the same value as the tool's Price Unit (ie 0.1985).



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. 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 Dynamic Gann Fan 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 Dynamic Gann Fan 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.

Price Flip: Allows you to create a duplicate of the tool along the price axis.

Time Flip: Allows you to create a duplicate of the tool along the time axis.

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 Dynamic Gann Fan 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. 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.

Price Unit: This is the value of one unit of price used in the tool's calculation. Manually enter a value to change, or click the end for the 1 x 1 line to recalculate between two points.

Apply Price Unit to Chart: When this box is checked all Gann tools added to the chart will be automatically calculated using the same Price Unit.

Data Type: Sets the data style used in calculating the Dynamic Gann Fan Angles. Can be set to either Bars (e.g. trading days, weeks) or Calendar Days.

Extend Lines: Check this box to automatically extend the angle lines.

Show Labels: Check this box to display the price and line values. Uncheck the box to hide these values.

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

Reverse Prices: Check this box to display the price values in reverse e.g. 8 x 1 instead of 1 x 8.

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

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.
