Reverse RSI

Author: Optuma Team Last updated: May 15, 2024 09:50


Based on the work of Giorgos Siligardos, the Reverse RSI tool plots the value on the chart at which the price needs to be to have a certain RSI value. This can be used to provide potential support and resistance levels based on RSI.

By default the tool uses a 14 period RSI value of 50. In this example of Microsoft the price is above the green Reverse RSI line, meaning the current RSI(14) is above 50. As we can see in the RSI below the chart the current value is 58.31, so for MSFT to reach an RSI(14) level of 50 would require the price to fall to 411.88:


To add the tool to your chart, select it from the Price tool group, and left-click on the chart and Optuma will then draw the tool using the default settings.

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

Apply Settings to All: When multiple Reverse RSI 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 Reverse RSI 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 Reverse RSI to a chart, the tool will display using the new settings.

Delete: Deletes the tool from the chart.
