Hurst Phasing


Hurst Phasing is more of a process than a tool. While we add it to a chart like any other indicator, there is an enormous amount of work and understanding which is needed to used when phasing a market. Our plan is to provide a video course on this but we have no ETA at this stage.

JM Hurst - a NASA data scientist in the 60's and 70's - outlines phasing in his books. It is used to identify major cycle bottoms. Hurst applies the principle of harmonicity to say that there should be cycles at related higher and lower harmonics. Once the first (dominant) cycle is phased correctly, adding these harmonic cycles becomes easy.

A confluence of cycles make it extremely likely that a major low will be seen in the market.

To apply the Hurst Phasing tool to your chart, left click on the Tools menu, go to the Hurst tool group and select Hurst Phasing.  The tool will be applied below the main chart.

Actions & Properties


Add New Row: Allows you to add an additional row using a subset of the initial cycle. The options included are 1/3, 1/2, 1/5, x2, x3 and x5.

Add to Toolbar: Click this action to add the selected custom Hurst Phasing tool to your custom toolbar.

Apply Settings to All: When multiple Hurst Phasing 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 hiding or adding levels- as this allows all the other Hurst Phasing tools in the chart, page or entire workbook to be updated instantly.

Copy Tool: Allows you to copy the selected Hurst Phasing tool, which can then be pasted onto a different chart window.

Delete: Delete the Hurst Phasing tool from the chart.

Hide Diamond: Allows you to hide the selected Diamond from the Hurst Phasing tool (turning it into an X).  Clicking the Action again will restore the diamonds default view.

Move to Back: If the symbols of the tool are displaying in front of other tools or indicators clicking this action will move the symbols view to the background.

Move to Front: If the symbols of the tool are displaying behind other tools or indicators on the chart, clicking this action will bring the symbols to the forefront.

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

Save Settings as Default: If you have adjusted any of the Hurst Phasing properties (colour, for example) you can save the adjustments as your new default setting. Each time you apply a new Hurst Phasing tool to a chart, the tool will display using the new settings.

Set Time Alert: Sets a time alert for the selected symbol. For more information on Time Alerts, click here.


Tool Name: Allows you to adjust the name of the tool, as it’s displayed in the Structure Panel.

Cycles: Here you can edit, add or remove levels to the Hurst Phasing tool. Levels can have their colour adjusted from this same window.

Max Cycles: Sets the maximum number of bars the default cycle can cover between diamonds (the minimum is 10).  The default cycle length is set by the top coefficient of the Periodgram cycle tool (using the same number of bars, non-log).

Calc Style: Allows you to set the cycle count between using Trading Days (Bars) and Calendar Days.

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.

Show in Price Scale: Allows you to display the cycle counts for each row in the tools price scale, highlighted in the same colour as the row(s).  The label will show a d for Calendar Days and and a b for Bars.
