Using exponential for ATR

[Stok]

Hi...when using ATR, I want the average to be calculated exponentially....I do not see that option in properties, is this something that would need to be done in NS?

Hello Stok,

Yes, if you would like to change the way the ATR is calculated you would have to create a new indicator using NinjaScript.

You may view the link below for more information about the ATR Indicator.

Note that you can view this indicator method source code by selecting the menu Tools > Edit NinjaScript > Indicator within the NinjaTrader Control Center window and double click on the indicator.

Let us know if we can be of further assistance.

I am just now coming back around to getting this programmed. I have looked at the NS for ATR, but I cannot figure out what to do to make it calculate the MA of ATR exponentially. Any help/direction?

Hello Stok,

I am not quite sure what you have having trouble with but please note that you may view the code of our EMA ( Exponential Moving Average ) indicator as well.

Happy to be of further assistance.

I do not know NS very well (I do know Easy Language), and would have to learn it at some point. It seems to me if I want a EMA of the ATR, there is no place in the ATR NS to do that.....it looks like it would take a whole other custom indicator. Honestly, I am looking for some simple help to modifying a few canned indicators, not building brand new ones.

Hello Stok,

If you are new to NinjaScript you may view the following thread that has some great links to help you get started with NinjaScript.

While, yes it would require a New NinjaScript file in order for it to be calculated you may use the Indicators that are already prebuilt for the calculations. For Example:

#region Variables
       private int aTRPeriod = 14; // Default setting for ATRPeriod
       private int eMAPeriod = 7; // Default setting for EMAPeriod
#endregion

   
protected override void Initialize()
{
      Add(new Plot(Color.FromKnownColor(KnownColor.Orange), PlotStyle.Line, "Plot0"));
      Overlay				= false;
}

protected override void OnBarUpdate()
{
     Plot0.Set(EMA(ATR(ATRPeriod),EMAPeriod)[0]);
}
