Changing the ATR Indicator

[678Red]

Hi All,

How would I create an indicator that gives me half the value of the ATR. Everything else stays the same.

Is there a way of simply using the existing ATR indicator you have, or would it need writing from scratch. If so, how would I do that.

Many thanks for your help.

PS. I appreciate I could just load the ATR and do the sum mentally, but as I use it constantly in my trading, to have this "correct" value already there would greatly help.

Hello 678Red,

Welcome to the NinjaTrader forums!

private double halfATR;
halfATR = ATR(14)[0] / 2;
Print(halfATR);

If you are setting a plot value this would be Value[0] = halfATR;.

If you are new to programming NinjaScripts, below is a link to a forum post with helpful resources on getting started with NinjaScript and C#.

Thanks for your help, but to be honest I have no idea what I'm doing here.

I tried creating a new indicator and entered the code you mentioned in your post, just a load of errors.

Hello 678Red,

Make new indicator.

In State.SetDefaults add:
AddPlot(Brushes.Blue, "myPlot");

In OnBarUpdate() add:
Value[0] = ATR(14)[0] / 2;

Brilliant. It actually works. many thanks for your help.

Hi
I feel dumb here but this does'nt work on my indicator.
I have set the variable, added the plot and added the value in OnBarUpdate (on first tick of bar) - all compiles and runs but no output?

Where could I be going wrong.

Hello Mindset,

What variable have you set? Are you referring to the Value series for the current bar?

Are you getting errors in the NinjaScript Output window?

Do you have more code than what I suggested above?
