Volume Bars

[Ace2231]

Can I make the volume bars colored based on the price action of the bar - green is an up bar or candle, red is a down bar or candle...

Hello Ace2231,

Thanks for your post.

You could create a custom NinjaScript indicator to accomplish this.

AddPlot() would be used to add a plot to a custom NinjaScript indicator.

The value of the Volume indicator (VOL()[0]) could be assigned to the plot.

PlotBrushes could be used to set the color of the plot when a certain condition occurs.

To detect if the bar is an up bar, you would create a condition that checks if the Close price (Close[0]) is greater than the Open price (Open[0]). Then, call PlotBrushes inside that condition to change the color of the plot in your script.

To detect if the bar us a down bar, you would create a condition that checks if the Close price (Close[0]) is less than the Open price (Open[0]). Then, call PlotBrushes inside that condition to change the color of the plot.

See the help guide documentation below for more information.

The C# programming language is used for developing NinjaScript indicators and strategies.

To create a NinjaScript indicator, open a New > NinjaScript Editor window, select the '+' tab at the bottom of the Editor window, select 'New Indicator'. Then, you could set up as much of the indicator as possible in the Indicator Builder. This will create the framework of the indicator or strategy

Once you finish setting up as much as possible in the Indicator Builder, you must manually program the rest of the indicator.

If you are new to C#, to get a basic foundation for the concepts and syntax used in NinjaScript I would recommend this section of articles in our help guide first:
