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 (1x1). As such, the 1x1 line is often called the 45 degree line, but it will not appear as a geometric 45 degree line due to the scaling of the chart*.

Using a Price Unit of 1 on a daily chart the 1x1 line will move one unit up (or down if placed on a high) for every trading day, a 2x1 will move two price units per day, and a 1x2 line will draw the line one unit up (or down) every two days. These lines are often areas of support and resistance.

img0*Note: If the Price Unit of the Gann Fan is the same at the time/price ratio in the bottom-right corner of the screen then the 1x1 line will be a geometric 45 degrees. To keep the 1x1 a constant 45 degrees as the chart view is changed click the padlock to lock the chart’s time/price scaling.*

Clients with the advanced Gann tool module can use the Dynamic Gann Fan tool to control the 1x1 line, and thus easily calculate the Price Unit, or ‘speed’ of the move between two points.

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.

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

Delete: Deletes the tool from the chart.
