EMA of a calculated value

hello, need some help. I have an indicator that charts a fast EMA and a slow EMA. I want to calculate a third EMA of the difference between these two EMAs. my ninjascript coding skills are average ... so any assitance is greatly appreciated! An example would be awesome. thanks

Hello pman777,

Thank you for your post.

You could use something similar to the following:

        protected override void Initialize()
        {
			Add(new Plot(Color.Blue, "MADiff"));
        }

        protected override void OnBarUpdate()
        {
			Value.Set(EMA(30)[0]-EMA(15)[0]);
        }
