MACD Histogram

[gdargento]

I've been trying to copy, rename (including the class name) and modify the MACD indicator that comes with Ninja to display the histogram only without success.

What controls what is displayed by the indicator? In the stock MACD I commented out part of the following in hopes of displaying only the hist:

//Add(new Plot(Color.Green, "Macd"));
//Add(new Plot(Color.DarkViolet, "Avg"));
Add(new Plot(new Pen(Color.Navy, 2), PlotStyle.Bar, "Diff"));

The result was a blank panel 2.

Thanks

Hi gdargento,

The reason you are getting a blank panel is because the Diff plot uses the Macd and Avg plots to calculate its value. This means you cannot simply comment out those two plots. What you need to do instead is change those plots into DataSeries instead. Using the DataSeries class allows you to maintain the plot values, but without the plotting graphics. You can review the exact details about them here: http://www.ninjatrader-support.com/H...taSeriesObject.

So basically this is what you want to do:
1) Add two DataSeries variables (Macd, Avg) to the Variables section.

private DataSeries     Macd;
private DataSeries     Avg;

2) In the Initialize() section you want to do

Macd = new DataSeries(this);
Avg = new DataSeries(this);

3) In the Initialize() section you want to delete/comment out those two plots you already did
4) In the Properties section you want to delete the first two blocks of "public DataSeries" (delete Avg and Default).
5) In the Properties section you want to modify the remaining DataSeries (Diff) to be placed into the proper index by replacing the 2 with a 0.

get { return Values[0]; }

Hope that helps. If you have any more questions please feel free to ask.
