Is it possible to make an indicator using max function?

[hybinubt]

I want to calculate VOLMA using various time periods and create a line only with the highest values.
which means

max(VOLMA(period1), VOLMA(period2), VOLMA(period3), ... VOLMA(period100))


For example..

VOLMA(period1)= 50
VOLMA(period2)= 60
VOLMA(period3)= 65
....
VOLMA(period99)= 40
VOLMA(period100)= 90 (lets say this is the highest value among the 100 VOLMAs)

Then, in this case

max(VOLMA(period1), VOLMA(period2), VOLMA(period3), ... VOLMA(period100))

will be 90.

Is it possible to make this kind of custom indicator?

Hello hybinubt,

Welcome to the NinjaTrader forums!

I've moved your thread from Platform Technical Support section of the forums to the Indicator Development of the forums as this pertains to indicator development.

The MAX() indicator returns the highest bar value for a single series.

However, you might be able to use a List<double> object and find the largest value with the Linq Enumerable.Max() method.

https://learn.microsoft.com/en-us/dotnet/api/system.linq.enumerable.max?view=netframework-4.8

List<double> myList = new List<double>() { VOLMA(50)[0], VOLMA(60)[0], VOLMA(100)[0] };
Print(myList.Max());

While I want to use SMA when I calculate that, I found that moving average of Volume(=VOLMA) is calculated using EMA in Ninjatrader.
Can you please make a code for indicator that displays max value among the various period (for example: period20 period60 period120) Simple Moving Average of Volume? (The values should be displayed in the same panel as the one with the volume)
I would appreciate if you could give me the complete code like below.

namespace NinjaTrader.NinjaScript.Indicators
{
public class Maxvolma : Indicator
{
protected override void OnStateChange()
{
if (State == State.SetDefaults)
{
Description = @"";
Name = "Maxvolma";
Calculate = Calculate.OnBarClose;
IsOverlay = false;
DisplayInDataBox = true;
DrawOnPricePanel = true;
DrawHorizontalGridLines = true;
DrawVerticalGridLines = true;
PaintPriceMarkers = true;
ScaleJustification = NinjaTrader.Gui.Chart.ScaleJustification.Right;
//Disable this property if your indicator requires custom values that cumulate with each new market data event.
//See Help Guide for additional information.
IsSuspendedWhileInactive = true;
}
else if (State == State.Configure)
{
}
}

protected override void OnBarUpdate()
{
//Add your custom indicator logic here.
}
}
}

Hello hybinubt,

I've copied and pasted the code I've suggested in post # 2 into OnBarUpdate() and exported this to assist in understanding how to get the Max value of multiple indicator instances.
LinqMaxTest_NT8.zip

This prints the value to the output window.

You'll need to adapt this to the needs of your script.
