Coloring rule for Volume of quantity of contracts traded

[ErlonAb]

Hello everyone,

I am switching to using NinjaTrader and trading in other markets. On another platform I use a rule for coloring the bars and the Volume Histogram. Something like a heatmap.

Basically it is a weighted average of the last 400 periods (bars of the histogram) and incremented with standard deviation calculations. And that paints the bars in warmer colors indicating an increase in volume.

I have the Groovy script on which this indicator was made. I tried to transcribe it to C # in NinjaScript, but I was unsuccessful.

The image below shows the idea.

I would like help with clarifying how I can resolve this code.

Thanks!

Hello ErionAb,

Thank you for your post.

To clarify, are you wanting to know how to color the bars (candles) on the chart and how to color a plot, such as a Volume plot?

CandleOutlineBrush and Barbrush would be used to determine the color of the bars (candles). CandleOutLineBrush determines the border color of a bar. BarBrush determines the color inside the borders of a bar.

See the attached example demonstrating using CandleOutlineBrush and BarBrush.

Also, see the examples in the help guide documentation below for more information.

BarBrush - https://ninjatrader.com/support/help...8/barbrush.htm

Plots or PlotBrushes would be used to determine the color of a plot. Plots would be used to determine the color property of an entire plot. PlotBrushes would be used to determine the color property of specific segments of a plot.

Thanks BrandonH,

It has helped a lot. Just one more question how can I do the SMA calculation for the volume, to later calculate the standard deviation.

As shown in the image below, the coloring of the volume bars establishes the parameters for the price bars.

Hello ErionAb,

Thank you for your note.

You could determine what color segments of a plot are based on certain conditions by using PlotBrushes. First, you could call AddPlot() to add a plot to your script and assign the plot a value. Then, you would need to set up your condition(s) followed by calling PlotBrushes to change the color of the plot. Then, any time that condition becomes true, the plot color for that bar would change to the specified color.

You could reference an SMA value in your script using SMA() and then calculate the logic for your standard deviation levels and assign them to variables. Those variables would then be used to create your conditions for when you want to set PlotBrushes to change the color of a plot segment.

Thanks Brandon,

The NT8 really is extremely powerful. I have already created my indicator, but it is only painting the candles.

Is it possible to paint the bars of the VOL indicator?

Hello ErionAb,

Thank you for your note.

You could determine the color of a plot, such as the VOL plot, by using Plots or PlotBrushes.

See the attached example script which demonstrates using PlotBrushes to determine the color for segments of the VOL indicator when a certain condition returns true.

In State.Configure we initially set the VOL plot to dodger blue. Then we create a condition in OnBarUpdate() that checks if the current Close is greater than the current Open. If the condition returns true, that plot segment for the VOL indicator is painted a goldenrod color using PlotBrushes.
