Changing color to a Volume Bar depending on volume

[dylan29]

Hi there!

Is there any way to add a property to VOL indicator that could change the colour of a bar if the volume is greater or equal a certain volume?

For example, if volume is greater or equal to 4000, I want the bar of this volume to be coloured on RED.

Any help?

Hello dylan29,

Thanks for your post and welcome to the NinjaTrader forums!

It is possible to create this, however, it would involve creating a custom coded indicator.

The standard VOL indicator is locked and cannot be changed. You are welcome to make a copy of the indicator and in its code, you can add conditional code that will color the bar based on conditions you configure. You can add a property to select the value of volume at which to color the bar as well as a property to select the color of the bar.

If you would like to create this yourself, we can provide you with links to get you started in Ninjascript which is based on C# programming language.

Alternatively, if you would like it created for you, we can provide links to 3rd party developers.

Also, while it does not provide specifically what you are looking for, here is an example of coloring the volume bars and may be of interest to you: https://ninjatrader.com/support/foru...d=7&linkid=681

Thanks for the reply!,

I would appreciate if you could bring me some guidance on how to clone the VOL indicator and tweak the code to colour the bar based on a certain volume.

Thanks again!

Hello dylan29,

Thanks for your reply.

To copy a script, go to New>Ninjascript editor. In the Ninjascript explorer panel, double left click on the indicators folder. Locate the indicator VOL and double left click on it to open the script. In the text of the script, right mouse click and select "Save as..." and provide a new name for the indicator (such as "myVol") and click OK. This will create the copy and now you can directly edit the script (as the editor replaced the VOL script with your newly copied script).

To change the color of the plot on a conditional basis you would use PlotBrushes, here is a link with example to PlotBrushes: https://ninjatrader.com/support/help...lotbrushes.htm

Please let us know if you need the "links to get you started in Ninjascript which is based on C# programming language."
