I haven't programmed in a decade or so. Thought I would give NT a try with what I thought was a simple indicator that I couldn't find, Larry Williams Accumulation Distribution.

Attached is the code for the Williams AD with a ZLEMA. The code compiles but it won't plot. I'm sure there's something simple that I'm missing.

Any assistance is appreciated with the simple task that has turned into a challenge.

You don't want to define a data series for the plots in the variables or initialize section, so you can delete lines 29, 30, 49, 50. For the most part you only need to define a dataseries in these sections for calculations where you want to reference a prior period for that calculation. The plots and input parameters are defined in a properties region inserted after the initialize region. For this one you would need to add:

 

Code

#region Properties [Browsable(false)] [XmlIgnore()] public DataSeries AD { get { return Values[0]; } } [Browsable(false)] [XmlIgnore()] public DataSeries ADMA { get { return Values[1]; } } [Description("Period")] [GridCategory("Parameters")] public int Period { get { return period; } set { period = Math.Max(1, value); } } #endregion

I don't really know why it's this way, I just know that's how you do it.

That produced errors, attached, with updated code.

All fixed and posted in the indicators section.

Does anyone know where this indicator is located ?
I did a search but could not find it.
Thanks

Try a different search parameter in the indicators. I believe I labeled it starting with "Larry Williams ......."
