no indicator on the chart

[randomwalker]

I code an indicator and get the message "indicator successfully generated", but I just cannot see anything on my chart. The following is my codes.


public class divwp2 : Indicator
{
#region Variables
// Wizard generated variables
// User defined variables (add any user defined variables below)

Add(new Plot(Color.FromKnownColor(KnownColor.DarkViolet), PlotStyle.Line, "Vvavg"));

protected override void OnBarUpdate()
{
// Use this method for calculating your indicator values. Assign a value to each
// plot below by replacing 'Close[0]' with your own formula.
double vVWAP = VWAP().VWAPLine[0];
dVWAP.Set((Close[0] - vVWAP) / vVWAP);
double edVWAP = EMA(dVWAP,12)[0];
double eddVWAP = EMA(dVWAP,26)[0];

Vvmacd.Set(fastdVWAP[0] - slowdVWAP[0]);
Vvavg.Set(EMA(Vvmacd,9)[0]);

Vvdiff.Set(Vvmacd[0] - Vvavg[0]);

Hello,

I'd work backward from your .Set statements and Print() all the input values to see if they are giving you what you think they should.

I looked over it quickly and didn't see anything that stuck out to me. I am sorry we don't really debug entire systems for people. I you have a specific question, I can help with that.

Hello,

My specific question is that I cannot see those .Set statements getting plot on chart, and also nothing showing up in the Databox. That is why I need your guys help.

randomwalker,

The reason is because you aren't setting the values to the plots. You are setting values to DataSeries objects which do not chart. They are just internal objects for you to store values on. If you want to actually plot them you need to use the plot's DataSeries objects.

According to your code in the Properties region the name for those plots are Vmacd, Vavg, Vdiff, and Zeroline. In OnBarUpdate() you are not setting to any of those plots. You are setting to Vvmacd, Vvavg, and Vvdiff which are different.

Thank you very much ,Josh and Ben, it works now.
