externally accessible custom indicator variable?

[Lost Trader]

a custom indicator VolumePRV calculates an estimated Volume & plots it.
Inside this custom indicator is a private (double) variable, that I need to make publicly accessible for other Indicators & Strategies. Thus far, nothing I've tried has worked.

Is there an example I may look at that does this?

Thanks!

You can expose it as a public property. Something like this:

[Browsable(false)]
[XmlIgnore()]
public double ExposedVariable
{
    get { Update(); return exposedVariable; }
}

This would generally go in the "Properties" segment of your code. "exposedVariable" would be your private variable.

Ah, I had something similar without the [] stmts & in Misc instead of properties. Rewrote it to match, thanks!

However, how do I use it?
In another indicator to use it, I tried simply
double PRVol = VolumePRV.PRV();
= VolumePRV.PRV; // Ninjascript fills it in this way

neither will compile. I even tried it w/o the VolumePRV prefix but it really didn't like that.

It is listed in my choices in the Ninjascript Intellisense list box as a double, but I can't seem to use it?

OK, I tried this:
private VolumePRV V = new VolumePRV();
PRVol = V.PRV;

It compiles but V.PRV is always 0.

Are there examples in the existing indicators that I can examine?

Well phooey. I gave up & took a different path. I copied your BOP indicator & changed the name to PRV, plugged in the correct calculation and it works. I use call this PRV indicator in other indicators and presumably strategies & market analysis since your code covers all that.
Don't even have to add it to a chart.

A better choice anyway for what we needed.

Cheers!

For the record this is how you would do it:

double indVal = IndicatorName().exposedVariable;

The parenthesis goes with the indicator method. The exposed variable is just a property of that method. There are no indexes that goes with it.
